“The Ten Year Affair” by Erin Somers is described as a story about "two young parents, both happily married (just not to each other), which sparks a will-they-won’t-they romance—perfect for fans of "Big Swiss" and "Acts of Service." However, I think this description may not capture the vibe. While it does have a messy protaganist, fans of *Sliding Doors* or Miranda July's *All Fours* might enjoy this modern exploration of married life more accurately.

That said, I may not be the target audience for this novel, as it made me very happy to be childless and queer. While I can understand the journey of self-reflection and pondering the “what-ifs” in life, I feel this story would work better as a short story. In novel form, I struggled with the pacing and found myself put off by what began to feel like the privileged whining about the choices they made. Much like their persistent bathroom fungus that they never deal with, the couples keep avoiding their issues instead of confronting their malaise.

I appreciated the snark in this book and would have liked even more of it. Overall, I would recommend this novel to those looking to vent about the challenges of adulthood, particularly those expressing the heteronormative complaints of well-educated, white, upper-middle-class individuals.

I enjoyed the writing style and the creative take on the contrast between current reality and the sliding doors concept. I believe others may appreciate this story more than I did. Thank you to Simon and Schuster and NetGalley for the ARC in exchange for an honest review. 3.5 stars

Just what I was in the mood for - entertaining and sometimes laugh out loud funny. Cora lives with her husband and two young children in the Hudson Valley and meets Sam at a parents' group -there is attraction and cracking chemistry. Do they have an affair? The timeline splits, sometimes on the same page, so we get to see the reality vs. the "other" and it really worked for me. The 10 chapters take us through 10 years in Cora's life and I loved the day to day details of raising young children in suburbia. This was a treat to read as an advance copy from NetGalley and the publisher.

This book was designed fiber as a sliding doors type of novel. In one timeline, Cora is a married woman with a crush on Sam and in the other she is having an affair with Sam. The writing is strong and evocative and you get a good sense of the four main characters. Unfortunately though the more I got to know them the less I liked them and I raced through the last quarter to get the book over with. 3.5 rounded up to 4.

This is a lovely story about a romance between 2 people who meet in a childcare group. Cora andSam are in charge of their newborns while their spouses are out working away from home. Slowly a relationship develops between them. It has aspects of fantasy and reality.

Cora becomes involved with Sam’s spouse, her very close friend. This does confuse me. Years pass and their relationship evolves. During Covid tge families shelter as a pod. Both couples are in their own difficult spousal relationships.

As a reader, I was thinking of their future, together or not? I was very satisfied with the way Somers brought it to closure.

I really enjoyed the book and I suspect many people have had relationships, real or imagined with people who aren’t their spouses.

Thank you Netgalley for this very compelling novel.

Naturally, it’s about an affair, because what’s more millennial than emotional complexity and confusion underlined by a persistent “what if”? Yet, the book isn’t really interested in the affair itself, not really. That part is practically a footnote. The real focus is on the long, slow burn of wanting: the protracted prelude where Cora, our protagonist, survives the gray hum of domestic life by mentally staging a decades-long romantic epic with her neighbor, Sam.

This isn’t your run-of-the-mill sordid kind of daydream. Cora’s fantasies aren’t cheap thrills, they’re serialized drama. Every time she checks out of her real life, she checks back into a parallel universe where their relationship has evolved: year by imagined year, complete with conflict, tenderness, and the kind of intimacy that feels earned. It’s less erotica, more emotional fan fiction.

There’s something powerfully millennial about the whole thing: this insistence on crafting an inner world rich enough to survive the disappointments of the real one. Cora doesn’t just want her charming neighbor. She wants the version of herself that exists when she’s with him in her mind: braver, freer, not folding laundry in yesterday’s leggings. Because when the world hands you monotony, you build a myth— and millennial women? We’re excellent mythmakers. Dry humor, simmering rage, and all.

“The Ten Year Affair” by Erin Somers (my first time reading her > hopefully not the last!! ),
…. is messy and naughty—filled with lies and betrayal, illicit affairs/extramarital forbidden relationships, passionate rendezvous infidelity….
married family life with kids, friendships, careers…..
taking place in a bourgeois small town with a community that embodies the characteristics of traditional values, independent artisans — stable, middle class existence. (a somewhat narrow-mindedness community and lack of diversity).
….It’s also juicy, witty, razor-sharp ingenious —(a few laugh-out-loud moments)…..
with edgy provocative characters.
I couldn’t put it down.

Don’t ask me ‘who’ (what characters), I was rooting for …. because….
“frankly, my dear, I didn’t give a damn”…..
I simply had SOOOO MUCH FUN READING IT!!!
(this coming from a 73 year-old woman, married for 46 years with no adultery issues)

“It had been about the two of them, and it had been about sex. But what it had been about mostly was her life. Escaping it. Not that her life was stultifying or anything, but actually it was. The storybook town, the twenty-first-century marriage between friends.
She had to designed it, wanted it, set it into place, expected it to have meaning, and then it hadn’t”.

It was not always so easy to make a standing sex date.
Their kids had activities—soccer, karate, etc.
“Did they really have to list all the reasons it was wrong? Was it not obvious? Was this not a common bourgeois scenario? Had they not already talked out the ripple effects on every person in their lives?”

“As reality splits, the everyday details of Cora‘s life—her depressing marketing job, her daughter‘s new fascination with the afterlife, her husband‘s obsession with podcasts about the history of rope—gain fresh perspective. The intercepting and diverging timelines blur the boundaries of reality and fantasy, questioning what might have been and what truly matters”.

….”What place did morality have in an affair?”
….”What did grief do to the world of the affair?”
….”Or an abortion?”
….Do we really want our fantasies to come true?
And….
….How do we continue to choose to love the people we have chosen, to not feel trapped inside our choices?”

GREAT NOVEL ….
Erin Somers is the real deal!!! Her writing is sharp …. exploring perceptivity — cautiousness — astuteness - with great insightful wit!

4.5 stars rounded up.

There are two types of books I love. Some, I want to devour at the fastest pace possible—staying up way too late because I need to know what happens next. Others, like The Ten Year Affair, I want to savor slowly, letting them wrap around me like a favorite sweater. This is definitely the latter, and I'm not mad about it.

Erin Somers has written something that made me want to text all my friends immediately. Her prose is sharp and funny and devastating, often in the same sentence. She gets the particular exhaustion of modern marriage, the way you can live entire fantasy lives while loading the dishwasher. Cora, our protagonist, exists in multiple timelines simultaneously, and Somers captures this perfectly: "During the hour-long drama that she watched with Eliot, she was blowing Sam in the backseat of his car. While she was running out to pick up milk, she was running out to pick up milk so she could meet him in the dairy aisle of ShopRite and have him furtively put his hand up her skirt for thirty seconds before heading home." It's this doubling that makes the book feel so achingly real. Anyone who's ever felt trapped in the mundane while yearning for something else will recognize themselves here.

Here's the thing: I could not have cared less about the actual affair, but I was completely obsessed with Cora and her world. If messy women are having a literary moment (and they are), this is how you do it right. Cora is infuriating and relatable in equal measure, and Somers never asks us to like her or excuse her behavior. She just lets her exist in all her contradictory glory.

There's this moment where Cora reflects on always being praised for her "great personality": "You have a great personality. You know that?" Her whole life, people had railed on about her personality. Such a smart girl—woman! Such a smart woman. And funny. It got worse (better) as she got older. Kind, empathetic, a good parent. That was nice, right? That was what you wanted. But couldn't this one man objectify her?" This hit me like a truck. The burden of being the "good" woman, the one everyone thinks is so smart and funny, when sometimes you just want someone to want you for something more basic and immediate.

Somers absolutely nails the small indignities of domestic life in ways that made me laugh and then feel personally attacked. Like when she describes how long it would take Cora to work up the energy to call a clown: "It would take Cora hours to work up the energy to call a clown. She'd have to block out a whole day for it. It would involve confronting the choices she'd made in life up until that point, the entire chain of events that had led to calling a clown." Like, girl, same. These moments are where the novel becomes something bigger than its premise—a meditation on how we end up where we are and how even the smallest tasks can feel like confrontations with our entire existence.

The marriage between Cora and Eliot is handled with such careful attention to both of their struggles. As someone who's dealt with mental health challenges, I appreciated how thoughtfully Somers approaches Eliot's depression and its impact on their relationship. Where this could have been a fantasy about grand passion and transformation (I'm looking at you Anaïs Nin and Annie Ernaux), Somers gives us something more honest: the mundane reality of how affairs actually function. Not as earth-shattering romance but as another kind of routine, another way of getting through the day.

The Hudson Valley setting was chef's kiss perfect. As someone who's spent plenty of time in these towns, Somers captures the social dynamics with laser precision: "You had friends and saw them for dinner. One party hosted and the other brought wine. You discussed current events while the kids watched a movie in a distant room. At the end of the night, you lay in bed talking about the other couple." It's so specific and so universal at the same time. You know exactly these people and exactly these dinner parties.

Near the end, Cora has what Somers calls a "radical thought: to reside in a single timeline. To do only what she was doing and not a second activity as well. To respect the laws of time and space." Presence itself is revolutionary. It's not about the affair ending or beginning, but about the possibility of just... being where you are.

Consider me officially an Erin Somers stan. This is the kind of debut that makes you want to corner strangers at bookstores and insist they read it immediately. Smart, funny, devastating, and completely addictive. I'm already counting down the days until her next book.

I really enjoyed this book. The dynamic between Cora and Sam pulled me in from the beginning, and I liked the way that the book moved through time. Even though it covered many years, I was never jarred by the passing of time. This was different than a lot of books that I've read lately, and will stay in my mind. Thank you NetGalley and Simon & Schuster for this ARC!

Cora and Sam meet at a baby class; there is an instant connection as they both hate the same mom. They begin having an affair that lasts ten years. At the same time, they don’t, and Cora stays faithful to her husband Eliot. And so this narrative intertwines two scenarios.

I was expecting this to be like The Names, where each chapter described each scenario and they were all cohesive stories. But this is different, the narrative switches within the paragraph at times, showing the reader what was happening. This definitely is confusing, but also creative. They aren’t that different, no butterfly effect here. I was so invested in Cora and Sam’s romance, although it was destined to end badly.

Who among us hasn’t looked back and wondered what could have been?

*Just finished *The Ten Year Affair* by Erin Somers and wow—what a ride.** This book quietly sneaks up on you with its sharp observations about friendship, longing, and the paths we *almost* take. It’s witty, bittersweet, and so well-written. Perfect if you’re in the mood for something smart but emotionally real.

Thank you to NetGalley and Simon & Shuster for the ARC!

Wow, this is everything I love in a book! I loved each character in their own right, the timeline/plot moved at the perfect pace, it was JUICY, and spicy. I ate this up and left zero crumbs.

I did not want it to end, but I was satisfied with the ending.

I would love to see this as a tv show or movie!

I am in awe of this book. It somehow manages to be funny, insightful, and deeply moving all within this messy story of a “ten year affair.” I LOVED the sliding glass door aspect and the way that things sometimes felt a little muddled and confusing as the timelines converged and separated. For all intents and purposes, Cora should be an unlikeable character, but I felt so deeply for her and the way that it’s so easy for people to lose themselves in the aftermath of what you imagine to be the perfect life.

The tension and build up in the book was great, and my heart broke for the way in which you know deep in your heart that Cora and Sam are not meant to be together; but it doesn’t matter. Some part of you understands their connection and devotion to one another and the way that the other person offers something that is missing.

This book won’t be for everybody but I think it does a brilliant job demonstrating the complexities of human relationships and how people are not inherently good or bad but make decisions that can sometimes be good or bad. I thought it was brilliantly written and hysterical and I’ll definitely be recommending this one.

Move over, Annie Ernaux. We have a new affair author in town.

The Ten Year Affair is, of course, about an affair. But few pages are dedicated to the affair itself. Most of the book is the yearning and fantasizing before the affair, presenting a dueling timeline in which our protagonist distracts herself from the banality of everyday life by fantasizing about her neighbor. These aren't the typical one-and-one fantasies where an illicit attraction is used purely as onanstic fodder. Instead, Cora builds a progressive, years-long fantasy where each time she indulges in her daydreams about Sam, their relationship in the fantasy world has grown and progressed.

In addition to telling an evocative story about the power of our imagination as it relates to our identity and relationships, Somers also captures bourgeois millennial masculinity astoundingly well. Cora appreciates that her partner is an equal, but finds a primal lacking in his respect for her inner life. The depictions of a small Hudson Valley town are apt and the writing is full of wit and insight.

I loved every second of this novel.

Thank you to NetGalley and Simon & Schuster for the e-arc.

The writing, exquisite. The characters, well formed (yet often times frustrating). The dynamic, extremely confusing at times. Do not read this if you don’t like an unlikeable cast. If you DO like that type of thing, read it now. This would have rated higher for me if the ending didn’t feel so rushed for me. The random cuts to different timelines did serve a purpose but threw me off, personally.

The Ten Year Affair is a wry, acerbic novel with observations on the anodyne aspects of aging, relationships, and fulfillment. I’m particularly partial to this style of writing, and I had a few chuckle out loud moments. The portrayals in the novel are a bit limited—the central characters are ostensibly white, middle class, and straight. Not a criticism, just an observation. I’d be curious to see what the author could do with broader characterizations.

I received a copy for review. All opinions are my own. An absolutely beautiful book….I could not pull myself away. So comical at times and very relatable, I really enjoyed the “dueling timelines”. This is one of those books that at the very basic level, is about people being…. Well…. People… and their choices and their repercussions or lack thereof. I fell totally in love with pretty much every character. I couldn’t pick a favorite even if I tried. For anyone that loves books about the complexities of an affair… this book is absolutely for you!

Cora and Sam meet at a baby group and find they have a lot in common. Both parents of two young children, both working for mildly unfulfilling jobs, and both happily married to other people. But from the moment of their meeting, they feel a powerful connection with each other. The story splits into timelines: one in which they have an affair and another in which they resist acting on their attraction for each other. We see the timelines develop over ten years, with each of the alternative paths shedding light on how their life unfolds in other — on their respective marriages, children, jobs, and happiness.

This was a creative and insightful exploration of marriage and the transition from early adulthood, free from much responsibility and with the hope and excitement of the future all promising, to middle age, when the realities of day-to-day life and seeming constraints imposed by choices one has already made. The author deftly portrays Cora’s inner life, showing how she is both deeply perceptive but also frequently oblivious to her own feelings and those of the other people closest to her.

Highly recommended.

I enjoyed this book a lot! I thought it had great insight into the life of a young mother without making it only about that. Minus one star for the ending, which I found a bit confusing and ultimately slightly unsatisfying.

When I first started reading this, I didn't know if I would be sold on the writing, but when I couldn't put it down (I finished it in 4 hours), I realized it in fact was Somer's voice that kept me glued. It's blunt, it's witty, and the story she tells is complex and gives such an honest insight into young motherhood, female desire, and identity. I'm not sure this would be first on my recommendation list, but I'm glad to have read it and I'll definitely read more from her in the future.

I really tried to love this novel but it just didn't work out for me. While it was well written, I didn't connect with any of the character's to actually be invested in the conflict of this story.
