I just finished it and Gabriel and Effie are everything! 💕🥹

Highly recommend for fans of Evie Dunmore — there’s so much feminism and discussion of social issues.

Then our MMC Gabriel has worked himself up from nothing in the slums, ruthless and violent but also wanting to truly help his community. He gave me strong Kaz Brekker vibes, and his chemistry with Effie is off the charts.

Effie is a fantastic FMC, with a mission to bring down a nefarious lord. Gabriel loathes the lord too, but needs his support so is determined that Effie won’t succeed. They are drawn together, both keeping secrets from the other and at opposing efforts.

It’s seriously so good, people! I’ve read most of Mimi Matthews’ books and I think this is my new favorite!

I was thrilled to see I'd recieved the arc of this one, but my excitement decreased steadily as I made my way into the world of the Crinoline Academy. This one just took ages to open up and I'm not completely sure was worth the effort.

Loved the idea of this book and was not disappointed! This was a well done historical romance with a unique storyline. Effie and Gabriel’s banter was great which made it so easy to root for them. And the book flowed nicely the entire time. I would’ve liked a little more in depth information about the Academy and the some of the characters but I’m sure some of that will come in the next book. Overall a great read.

Thank you to Berkley Publishing Group and NetGalley for the ARC!

"Effie supposed she shouldn’t have noticed it. Then again, knowing one’s surroundings meant noticing everything in them, even if that everything included the bare neck of one’s brooding would-be rescuer."

He's not exactly a gentleman; she's not exactly a lady of refinement. They're both playing-acting at a role in society, but their intentions just might get in the way of each other's plans!

Mimi delivering a proper regency romance with not-quite proper ladies and gents. Pining! Finding ways to be in each other’s company! Secret kisses! Dashing rescues! A very loveable pooch! Taking down a scoundrel! Swoony eye contact!

It was adorable.

"She had the uneasy sensation that the fundamental topography of their acquaintance had undergone a seismic shift. It was more than a change of perception. It was an alteration to the very ground on which they stood."

“Darling,” he said, “I’m yours to command.”

Not my favorite by Mimi Matthews, but this title was good and I enjoyed it. I wanted to love it - the premise is great, I liked the characters, and the setting was fine. I look forward to more titles from an author I like very much.

Mimi Matthews delivers another dazzling masterpiece with Rules for Ruin, a sharp, swoon-worthy tale that balances intrigue, social commentary, and undeniable chemistry.

Euphemia Flite is a heroine for the ages—fierce, clever, and bound by a past that fuels her desire for freedom. Her mission to dismantle a corrupt politician’s power is as daring as it is dangerous, and her unexpected sparring partner, Gabriel Royce, is every bit her match. Their battle of wits crackles with tension, while their slow-burn romance adds a delicious undercurrent of vulnerability and longing.

Set against the rich tapestry of Victorian London, Matthews weaves a story that’s as thought-provoking as it is entertaining, bringing the gritty streets of St. Giles and the glittering ballrooms of Mayfair vividly to life. Rules for Ruin is a perfect mix of action, passion, and empowerment—an absolute must-read for fans of historical romance with a rebellious twist.

I loved Mimi Matthews' Belles of London series and was excited to see the start of another series from her. I really enjoyed the set up and idea of an orphanage training women to avenge others. The middle of the book dragged a little for me but I loved the push and pull between Effie and Gabriel.

I loved this book! The main character are great! The storyline is great! It’s a fun lighthearted read! A must read!

Mimi does it again! I love the history and backstory that will continue to be explored in the companion books!

I loved the rivals aspect and the subterfuge and secret rendezvous. So fun and I loved how the romance built steadily.

As always, this author provides sweet yet substantial closed door romance.

Rules for Ruin shows a new direction for Mimi Matthews. It is very readable, and I am sure many of the author’s many fans will love this new direction.

I love Mimi Matthews but I can’t deny I was disappointed by Rules for Ruin. Matthews did a good job of writing a story that also addressed societal issues in The Matrimonial Advertisement, but I felt the societal issues overwhelmed the story in Rules for Ruin. It also felt like she was pushing the boundaries for acceptable behavior.

In addition, I found it hard to like either of the main characters, and Effie’s personality seemed very inconstant to me. She was cold as ice one moment and falling apart the next. While I understand people can be like that, it seemed unbelievable to me as written.

The relationship between Effie and Gabriel felt a bit too insta and almost like a teen romance. Too hot too fast – will this really last? And there were some truly over the top plot twists, maybe too many for this reader. I kind of felt like - if you are going to go there, go there! Full on fantastical steampunk adventures!

I will keep reading the author, and I’ll also reread her sweeter romances that focus on character development.

I read an advance reader copy of Rules for Ruin from Netgalley.

The romance is classic Mimi Matthews. It's clean yet stuffed with enough tension that you don't really miss the steam. I liked Effie and Gabriel (who gives off strong Tommy Shelby vibes) and thought their relationship progressed nicely. They each have their own secrets and objectives, and it was easy to invest in their push-pull dynamic. Additionally, the trademark fashion details and references to historical reforms, events, and even gentrification are seamlessly woven into the plot.

I love that Matthews tried something different, but the spy academy backdrop was kind of weak and the middle section dragged in pace. I didn't like Miss Corvus. To be fair, there's plenty to build on in future books, so I hope it goes better next time.

Matthews is back with a new series featuring strong resourceful women overturning rules to make their lives and the lives of other women better while finding romance with worthy men. Orphaned Effie Flite was raised in a peculiar orphanage for girls where she was given an excellent education including self defense. Leaving her position as a lady's companion in Paris, she and her little poodle go to London where she is introduced to society as the ward of a friend of her hostess. Viscount Compton, who is important if legislation is to be passed to allow women to control their own finances, is the object of Effie's investigation. Gabriel Royce who came up through the slums and runs gambling in The Rookery but has earned his way into society is trying to get support to improve conditions in the slums and is courting Compton's support by having letters and documents that could expose how he ruined and stole the fortune of a young woman several years earlier. A delightful combination of 19th century women's history and romance with a lovely dash of espionage.

This was so much fun!! I really did not know what to expect with this book but I loved Mimi Matthews’ previous books—and I was NOT disappointed. A must read.

An engaging historical romance and promising start to a new series. Betting shop owner Gabriel and society lady Effie enter a cat and mouse game in which both parties have secret agendas. Although there's an attraction between them, they can't quite trust each other. But they just might need each other.

I like the setup of vigilante debutantes released into society to exact revenge on the patriarchy. This book dragged a bit in the middle, but was a fun premise.

Thanks to Netgalley, the publisher, and the author for the ARC to review. All opinions are my own.

Mimi Matthews’ new series is a captivating story with intrigue, mystery, and well-developed, relatable characters. I couldn’t put this book down and eagerly await the next installment.

From the exotic cover to the suspenseful plot, this new series by one of my favorite authors seemed different. And loving the past Matthews works as I do, I wasn't sure different was a good thing. So you can understand why I was so happy to find that, though indeed different, this first new book has all the important qualities that I treasure in earlier Matthews books.

The writing is still as deft and the plotting as masterful. The writing is clear and compelling. And the romance is just as strong: immediate response between MCs and after a short bristly period, the MCs are committed for the long run.

While the book did feel different as I read, I quickly recognized Matthews' sure, steady hand at the helm of the narrative. I missed the "all or nothing" power of connection between the MCs (e.g. The Matrimonial Advertisement). But this book is compelling, and the new series will attract many NEW readers.

Coming out May 20 2025 - be ready!
Thanks for NetGalley and Berkley Publishers for the chance to read an advanced copy.

Thank you so much to the publisher for providing me with a digital review copy of this book via NetGalley.

I am a huge fan of Mimi Matthews's books, so I was super excited to hear about her new series. And Rules for Ruin was a lovely read! Effie was such a force of a character, and the relationship between her and Gabriel developed really nicely - a swoony, sharp, fight-for-each-other slow burn - everything you would want in a historical romance!

📣 a historical with a *sigh* working-class hero

Thanks to the publisher & Netgalley for the complimentary ARC. All opinions provided are my own.

📖 This book is part of the reason I’ve really been feeling historicals lately. Have any other recent historical reads I should check out??

Working-class historical leads make my heart go pitter-patter & Gabriel & Eddie are delicious ones.

Enticed by an offer of financial independence, Effie decides to help bring down a deserving man. Gabriel doesn’t like the aforementioned bad man, but he does want the bad man safe so that he can continue blackmailing him.

In Rules for Ruin, Mimi Matthews really makes me feel the attraction between Effie & Gabriel. He knows what he needs to do, but meanwhile there’s a gorgeous, mysterious figure named Effie he can’t get enough of. The chemistry between them is so good, steadily building in an intricate dance that leads beautifully to a much-desired HEA.

This one is so good, you all!

4.5 ⭐️. Out 05/20.

Mimi Matthews is in a class of her own. I adored Effie and Gabriel's romance, and I continue to be so impressed by the way Victorian London effortlessly comes alive through Matthews's meticulous research. I am very much looking forward to the next book in the Crinoline Academy series!

RULES FOR RUIN by Mimi Matthews
Rating: ⭐️⭐️⭐️⭐️⭐️

I had Great Expectations for this book and Mimi Matthews met them all! Like Dickens’ legendary character Miss Havisham who used her adopted daughter Estella to take her revenge on men, so does Miss Corvus. She even has the Crinoline Academy to teach young ladies to accomplish her aims. Her star pupil is Effie Flite and she tasks her to find incriminating evidence on Lord Compton who opposes the Married Women’s Act. Effie also searches for clues to her own past and that of her mother. She doesn’t plan on meeting Gabriel Royce, a slum lord who is determined to improve housing in the rookeries. Past, present, and futures collide when the pair fall in love. Another unforgettable story by Mimi Matthews. I cannot wait for the next book in the Crinoline Academy series.
