Thank you to HarperCollins and NetGalley for the opportunity to read this eARC!

This book far exceeded my expectations. From the very beginning, when we meet Miriam Richter, the stage is set for a dark, mysterious, and almost poetic tale. Miriam is a chillingly compelling character— a being who feeds on the souls of others through Faustian bargains. For her, this is survival. She feels no remorse, no emotion, no humanity… until she encounters Cybil.

Cybil is a lonely young woman, misunderstood and mistreated by her family, who believe she is cursed simply because she is the firstborn daughter in a long line of witches. This alleged curse dooms anyone she loves or grows close to, leaving her isolated and vulnerable. Miriam sees this as the perfect opportunity to manipulate her way into Cybil’s life, hoping to lure her into a bargain and ultimately claim her soul.

But the story takes a devastating turn. Cybil is killed during a witch-hunt and, with her dying breath, she enters into the bargain—binding her fate to Miriam. What follows is a hauntingly beautiful tale of reincarnation, obsession, and manipulation. Each time Cybil is reborn, Miriam hunts her, weaving herself into her life and trying to keep her from remembering the past. Miriam claims it is love, but the question lingers: can something so dark and soulless truly experience love?

The ending completely took me by surprise, and the entire story was both unique and thought-provoking. Dark, decadent, and emotionally charged—I couldn’t put it down.

⭐️⭐️⭐️⭐️ (4 stars)

This was pure fun. A curse that follows lifetimes and the quest for love is presented in such a beautiful way.

I really enjoyed this one! The story is beautifully written and full of emotion, with characters that feel real and deeply human. I loved the way Siegel weaves together themes of love, loss, and connection—it made the story feel heartfelt and meaningful.

The pacing is steady, and the narrative draws you in without feeling rushed. My only small critique is that a few parts felt a little predictable, but the writing and emotional depth more than make up for it.

Overall, it’s a touching and thoughtful read that left me thinking about the characters long after I finished the book. Definitely a solid 4 stars from me. 🌌📖

⭐️⭐️⭐️ ½

This was a well-written dark fantasy romance featuring detailed imagery and a few spicy moments. I enjoyed the dynamic between Miriam and Cybil/Esther/Rosamund. Unfortunately, the plot of second half of the book lacked substance for me. It felt like there was a missing action point. I was waiting for something new to occur but it did not happen until the very end of the book.

As Many Souls as Stars will be released on November 25th, 2025.

This was a dark, creepy and poetic romantasy about lovers reincarnated through time. A young lonely woman named Cybil sacrifices her soul to an immortal demon named Miriam in exchange for the gift of reincarnation.

Now Cybil is bound to Miriam for eternity and they begin their odyssey through time. Cybil is reincarnated as different women; Esther and Rosamund. Miriam remains in constant obsessive pursuit.

This was a beautifully written novel, I was mesmerized by the writing style.

Their love affair fell a little flat for me. I just don’t believe in love borne of so much darkness and manipulation. I wanted a softer side to emerge, I expected that and it never really happened for me.

I would have loved more descriptions of the backdrop of the different eras but that seemed to take a back seat to the toxic relationship.

Still I really think this author is quite talented and would entertain reading more from her in the future.

Dive into this darkly sensual fantasy romance featuring two women, a witch and a demon, who are bound in a Faustian bargain that crosses through time as each woman tries to outwit the other and outrun their own desires.

In a time lost to obscurity, a group of dark magic users summoned a dark creature that they intended to enslave for their own purposes. This being didn't exist, but their power demanded a result, and Miriam Richter is summoned into being from the dark thoughts and powers of those who imagined her. She quickly breaks her bonds and spends her days making Faustian deals to help feed the constant hunger for the light from humans' souls.

Miriam's path changes when she discovers Cybil, an extremely powerful First Daughter of her generation who is beset by a family curse. Miriam will do anything for Cybil's power, and in Cybil's dying moments, she makes a deal that Miriam can have her soul after she is reincarnated again. Cybil thinks that her two-souled reincarnation may have the power to defeat Miriam, and Miriam is confident that she can still win as she and Cybil attract and repel each other as light and darkness throughout time.

This book should appeal to fans of The Invisible Life of Addie LaRue, especially those who want a more heated and intense connection between the main characters. As each woman gets more emotionally invested, the tables turn and darkness and light become more a matter of whose perspective the light comes from.

Many thanks to HarperCollins and Netgalley for an advanced reader e-proof of this book for review purposes. All thoughts and opinions expressed are my own.

Mayhap this is exactly the book I wanted to read to usher in a more autumnal vibe! Natasha Siegel is a new author to me (although imagine my surprise when I realized I already had a book of hers on my physical TBR shelf) and she's definitely someone I'll be watching from now on.

From the first page, she showed a mastery of the craft that was almost lyrical. I sometimes struggle to visualize a novel but definitely didn't here, seeing it all play out with ease and a level of clarity I'm not used to. I found myself letting out a quick "Wow" under my breath every now and then out of surprise, and awe, with the words artfully being strung together.

Some parts of the final act left a little bit to be desired but I think that's partially my fault for building up the culmination of everything so much in my head. Ultimately, I can tell this book will stay with me and I'll be thinking about it a lot over the coming months.

Plus, it made me want to incorporate the word 'mayhap' in my everyday waaaaay more.

Thank you to NetGalley and William Morrow!

As Many Souls as Stars was a phenomenal book. I thoroughly enjoy books with deals, such as Addie LaRue and Our Infinite Fates. This one was no exception. The end of the book left me on the edge of my seat and I had no idea what was going to happen, until it did. Both Miriam and Cybil Harding (as well as other lifetimes) were interesting characters. It was amazing to see how smart Cybil became in the end and how far she grew throughout the novel. 4.5 stars.

WOW! I DEVOURED this book with a hunger I did not know I had, much like Miriam. The many lifetimes of Cybil were so distinct and different, and the constant question of what would happen next was constantly running through my mind. This book is amazing for any fans of Addie La Rue or anyone who loves a book with a Faustian bargain!

This book has me feeling very lukewarm. While I was reading it I enjoyed it, but nothing particularly pulled me to pick it up when I wasn’t reading. I don’t know if that makes sense. I appreciated the ending though it was predictable from the very beginning. This gave me small tastes of Our Infinite Fates, but if I’m honest this one was not quite so enthralling.

Overall, the writing was nice, the story was okay, the end result was just a lukewarm kind of book. It probably won’t stay with me very long.

Thank you to the publisher and Netgalley for the advanced review copy.

At the heart of this story is a romance. At the heart of this story is bitter enemies. Both can be true at once.

This book stretches through the ages, chronicling a deal for a soul - and a life. If you enjoy historical fantasy, you're in for a treat to see three different eras play out with the same characters. The magic is vivid and not without a cost, but entrancing just the same.

The real meat of this book is the characters and the inevitability that surrounds their lives. We all are who we are made to be. This book is ideal for those who enjoy dark romance, queer romance, fantasy in the real world, and historical fiction.

I'm looking forward to reading more of the author's work after having read this one, which is always a good sign when finishing a book. Highly recommended.

Harding and Richter's story is absolutely breathtaking and heartbreaking. Their love is gothic, toxic, deadly and enthralling. Siegel never shied away from how truly terrible and dangerous their romance was. Because to say it’s an unhealthy and obsessive romance is an understatement.

If you’ve read Siegel's previous two books, this one definitely different. There’s a lot more magic and fantastical elements, but her writing is still as poetic and beautiful as her other books.

Highly recommend!

Lesbian English majors rejoice—we have an actual, gorgeously sapphic Dr. Faustus in our midst.

Thanks very much to NetGalley for the advanced copy!

Natasha Siegel’s As Many Souls as Stars is a stunning feat of romantic fantasy—at once sweeping and intimate, haunting and tender. It’s a story that feels carved from stardust and shadow, perfect for fans of The Invisible Life of Addie LaRue, but with its own fierce, witchy heartbeat.

In Cybil Harding, we meet a girl cursed by birth and bound by legacy—powerful, bright, and defiant in a world that’s determined to break her. In Miriam Richter, we meet a demon made of longing and loneliness—immortal, hungry, and devastatingly human beneath the darkness. When their lives collide in 1592, it sparks a centuries-long chase, a soul-deep connection that defies time, logic, and even fate.

Their bargain—reincarnation for a soul—sets the stage for a gorgeously gothic game of cat and mouse, where every new life brings them closer to something neither dares to name: love, maybe, or something even more dangerous. The tension between them is exquisite, threaded with yearning, rage, and a fragile kind of hope. Think enemies-to-lovers, but across lifetimes, and with actual soul-bargaining on the line.

Siegel’s prose is atmospheric and lyrical, effortlessly shifting between timelines while anchoring everything in deeply felt emotion. The magic is rich and shadowy, but never overwhelms the story’s beating heart: two women navigating the unbearable weight of immortality, grief, and love.

💫 As Many Souls as Stars is a gothic epic and a tender meditation on fate, freedom, and the power of choosing each other—again and again. Let it enchant you, and don’t be surprised if it leaves a mark.

I wasn’t sure what drew me to As Many Souls as Stars, but something about it called to me the same way Miriam called to Cybil across time. This book being compared to Addie LaRue feels both accurate and inaccurate—while the changing world and Faustian deal were still there, the bond between Miriam and Cybil felt more tenuous, more like a choice each kept making over and over to return to the other even if out of spite. It’s the kind of book that whispers in your ear, walks in your dreams. It’s been haunting me since I finished it.

I really loved Siegel’s attention to all the little details in each time period. I can only imagine the research that went into each timeline and the worlds around them. All the winks and nudges that Cybil was and wasn’t the girl Miriam was waiting for, all the will-they-won’t-they made it almost impossible to put the book down even to sleep.

Above all else, I loved Cybil. I loved her wit, her brain, her compassion and self-sacrificing streak. I loved the complexity of her relationship with Miriam and how they became stuck in this ouroboros of love and hate, catch and chase. I loved how they completed each other as much as they repelled each other. I love that queer love and same-sex sexual relationships have become more common in fantasy and the way Siegel tackled each scene. I loved the ending, when I put the book down and rubbed at the goosebumps on my arms.

I loved this book deeply. Natasha Siegel has nabbed herself a lifelong fan, first in line for the preorder.

If you like toxic lesbians caught in a centuries long watching-and-waiting game, ancient magic and deals with the devil, you need to preorder this book today.

Thank you to William Morrow Books for this beautiful ARC and to Natasha Siegel for such a beautiful story!

Cybil is a cursed woman. A first born Harding daughter will always bring ruin. And even as she fights against the idea of the curse, men and society force her into this narrative. Meanwhile, Miriam, a demon bent on consuming souls, sees the brightness of Cybil’s and starts a quest to consume her soul. Bargains and centuries later, the two are still at odds with sexual tension to match the threatening tone of their relationship.

This book revels in the tension of these two hungry women in a world filled with violent and dismissive men. But at its core, this book is about what it means to love someone, and I’m still questioning the answer. Or even if there is an answer.

the gothic vibes are VIBING. This was a beautiful and poetic ride of a story, and adding toxic sapphics in there was the icing on top of the cake.

I loved the world building and atmosphere, but some of the story felt a little repetitive. Overall, it was an interesting and unique plot, so I enjoyed it.


I 100% recommend this book! It hits basically all of the right notes.

I truly think this book may be one of the best ones I've read.

The women in this story bring a fire that starts small and becomes an inferno. Natasha Siegel gives us loneliness and pain in a palpable manner. Cybil's yearning for the love of her parents, the urge to be free from the yoke of the burdens they put on her. Esther's wishes to be able to show the love she deeply feels without fear. Rosamund's desire to bring an end to a pantomime stretching centuries.

In the center of it all, Miriam Richter. A woman brought to being through arrogance and pain. The eye of the hurricane that batters and breaks what it touches.

These four threads weave a rich tapestry that is captivating and haunting. One that definitely has me wanting to start the story over again, and again.

Huge thank you to NetGalley and William Morrow for the eARC in exchange for an honest review!

A family curse, a Faustian deal, a mutual obsession that reaches through multiple lifetimes, AND its sapphic? Immediately yes.

Cybil Harding is born into a life of loneliness, grief, and melancholy as the misfortunate first born daughter of a family plagued by an ancient curse. Miriam Richter is the physical manifestation of darkness, summoned into being ages ago and burdened with an ancient curse of her own - immortality (and an insatiable hunger for souls). The two meet when Ritcher finds herself in the Harding home and crosses paths with Cybil, whose soul burns far brighter than any other Richter has ever come across, and she is determined to make a feast of it. Chaos ensues, and she makes a deal with Cybil in exchange for her deliciously luminous soul: another chance at life, so that she can try to break her family’s curse. But reincarnation only seems to amplify Cybil’s powers, and Richter is left chasing her across multiple lifetimes in an attempt to claim what was promised to her.

The writing is evocative, and I’m so impressed by how well developed the relationship between Harding and Richter was. The centuries-long mutual obsession and yearning were palpable. It’s said that opoosites attract, and this is especially true for light and darkness - as the two are all the more stark when contrasted by one another. I did feel like the pacing was a bit slow at times, but that could’ve just been because I was so eager to see how it’d end (and oh man, that ending!!)

I was admittedly hesitant when I saw this marketed toward lovers of The Invisible Life of Addie LaRue since I wasn’t a fan of that one, but this story had everything I personally felt like the former was missing and I’m so glad I gave it a chance.

This was overall a fantastic read, and I’ve already recommended it to multiple people who are now eagerly awaiting its release on Nov 25!

Finally, some toxic representation for the sapphic relationships out here in fiction!! As Many Souls As Stars is the story of Miriam and Cybil, a demon-adjacent and human respectively, but also so much more. I adored the way Siegel wrote Miriam's loose connection with existence, really shaping her to be a creature that is otherworldly and driven by entirely different motivations that a human couldn't even start to consider. On top of all that, we have that delicious helping of ennui which I am NEVER mad about. Cybil, the human counterpart, is part of your standard fantasy puritanical society, and together they are horrific. Mariam wants her soul, Cybil wants a break.

Except the story goes beyond these two, because as Cybil's arc began to wrap, I kept checking my progress to make sure something wasn't broken. I was barely a third, if that, through the book. When part 2 started, and I came to realize this was a story of recinarnation, I literally pumped my fist into the air. From there we see the soul that Miriam craves transform, living multiple lives that have a strong characterization that reminds you it started as Cybil, but now is someone new. I cannot recommend this read enough!
