Margin of Error
From Rachel Lacey, author of
Learning Curves
, comes a tender, hopeful romance about how fate is what you’re given but love is what you choose, and how small sparks can change everything.
Two years after an accident in Manhattan almost claimed her life, Marin is determined to take advantage of her second chance. She’s left her husband, her job, even her home to pursue the life she’s always wanted. Now she’s teaching statistics at Northshire University and preparing to do something she’s spent decades dreaming about: date a woman. But the last woman she expects to encounter on her journey is the one she’s been fantasizing about since their chance encounter the morning Marin nearly died.
Charlotte has made big changes in her life since that fateful day too. Most importantly, she’s moved back to her Vermont hometown, determined to finally solve the thirty-year-old mystery of her mother’s disappearance. An unexpected—and unexpectedly intense—friendship? That wasn’t in the plan. Neither was questioning her sexuality, but the more time Charlotte spends with Marin, the more she realizes her feelings run deeper than friendship.
Surely this would be a disaster, both of them being each other’s first, except the chemistry between them feels too strong to deny. But as they get to the heart of the mystery—and the heart of who they are—what brought them together just might tear them apart.

This book was fine. Even enjoyable with a good balance of romantic and steamy. But I’ve read four of the author’s books and I’ve seen a pattern emerging. In each books, she uses the same plot hook. The two main characters set clear boundaries on why they shouldn’t have sex. They’re collaborators, or colleagues, or employer/employee; or in this book, taking things slow while a character figures out her sexuality.
But then in the next chapter, it’s ‘fuck it,’ and they have sex anyway.
This bothers me, as it sets up a forbidden romance angle, but the reader knows that’s bullshit, which ruins the whole point. Instead, it’s a “why did you bother?”
The 3AB* was also brutal, and that’s ultimately a dealbreaker for me. Here, we’re supposed to be sympathetic to the first FMC, Charlotte, for what she’s going through at the moment, but all I thought was, “get your shit together, Charlotte.” The other FMC, Marin, as she’s getting rejected—again—tells Charlotte that this is not how two people who love each other tackle challenges. You're right, Marin.
3AB wreckage like this can often be turned around with important character growth. Not the case here. Charlotte realizes that she royally fucked up, and has to resort to the big-gun apology. As it turns out, an apology is not needed, as Marin loves her to the point of forgiveness. Great, but is that character growth? Or anything other than, aren’t you lucky she loves you anyway?
EDIT: After thinking about it, I’m bumping a Star and giving Lacey due props on both MCs seeking therapy near the conclusion of the book. That is character growth. Cheers.
SECOND EDIT: A comment below from @Danielle got me thinking. There really are two categories of readers. Casual readers, and readers who’ve dug in here on Goodreads and write reviews with a more critical eye, and include those critiques in reviews. Margin of Error is a great example of both. If you’re a casual reader, than this is a very enjoyable sapphic romance. If you’re a veteran GR Reviewer, you see the writing flaws in plot and character development. Both facts are true.
THIRD EDIT: I need to draw attention to my biggest pet-peeve. Cute pets on the cover. If the pet has no significance to the plot (or not even in the book!), it bothers me because I know it’s a ploy from the publisher to charm potential readers. Here in Margin of Error, sweet puppy Ember is huge to the plot of the story and I’m glad she made the cover. Cheers again.

The cure to my reading slump? It’s been a little while since I was this locked in to a book this hard. I pretty much knew from page one that this was going to be my next 5-star read.
I mean, finishing this was literally the first thing on my mind when I woke up in the morning.
I was a little but nervous to pick this up, because I have read a few short stories from Rachel Lacey in the past- and I did think they were good! But they didn’t “speak to me” I guess.
But let me tell you, I should NOT have been hesitant with this book. Because it absolutey ate on every single level, and with every single aspect.
I freaking loved this story, and I loved these characters even more.
It is somewhat rare that I feel a connection to both of the main characters in a romance novel, but here, I liked them both equally.
Both Charlotte and Marin both have incredible stories separately, and together!
I think Charlotte’s situation was really a great addition to this. It brought in some unexpected mystery, and some emotionality that took this to a new level for me.
Marin’s situation is so endearing. Reading about her plans and her goals of finally becoming the person she was meant to be after so much time pretending was beautiful.
The slow burn of this, did in fact burn me.
These two were actually perfect for each other, so the fact that it took so long for things to heat up? That is actually criminal! I was waiting like I have never waited before.
The end result was so worth it though.
My last note will be how awesome it is to read a story about these two finding themselves a little bit later in life (ish. Later compared to a lot of other romance novels)
They are 40 and 47 (if I remember correctly), and are still discovering who they are, what they like, and sort of “restarting life”.
I think this is pretty awesome, and a nice deviation from the idea that everyone has picture-perfect, “figured out” life by then.
Kudos to them, and to everyone else with new beginnings!
Thank you to Netgalley, Montlake, and author Rachel Lacey, for providing me with the eARC of “Margin of Error” in exchange for my honest review!

⭐️⭐️⭐️⭐️⭐️
I am convinced that Rachel Lacey only writes masterpieces.
Firstly, I loved how characters from her other books were briefly mentioned. It makes me feel like I'm diving into a little world that I never want to leave!
As I said, Rachel Lacey is my absolute favorite author, and with this book she has shown me once again why. No other author can make me feel the same emotions as her books do!
I really liked the plot of the story. Novels where older women discover their sexuality are so desperately needed, and I think Rachel Lacey has done an excellent job of representing this! The book had a perfect balance of action and sweet moments.

I went into this one super excited; the premise sounded so promising, and that first meeting had me hooked! But after the FMCs' second encounter... things just slowed way down for me. The mystery subplot tried its best, but it wasn't enough to pull me back in, so I stayed pretty underwhelmed overall. Still appreciate the vibes though!

Review of advance copy received from NetGalley
I loved the prologue scene, without knowing it, Charlotte and Marin are linked for life in a scary and strong scene. The fate factor played a strong part in their story, to put them on the same path again. I like when authors don’t torture me for chapters for the characters to interact with each other. The friendship they develop was really sweet to read and I love how Charlotte cames to terms with her, the jealousy, the self talk. Marin is really likeable too, and I know a lot of women coming out late in life will recognize themselves in her. I really felt the nerves and the exiliration to finally live her truth. The story around Charlotte’s mother added some mystery, but I expected something deeper. I wasn’t a fan of the fight in the end that felt a bit unecessary to me. Lacey’s book are always plaisant and easy to read.

Interesting story of two 40 year olds finding their true selves: well written with angst and puppy humour. Even at 40+ the fear of being different resonates.

🎊🎊🎊Happy Publication Day! 2/3/26 🎊🎊🎊
7/10: 3.5⭐️’s rounded up to 4⭐️’s
Do you believe in fate?
Charlotte: Always searching, always drifting (aka running?)
Marin: Always go with the flow and do what’s expected of her.
They meet on a bus and strike up a short, but meaningful conversation to the both of them. Marin gets off the bus and is hit by a car. Charlotte rushes to her and holds her hand as she lay on the cold snowy ground dying while waiting for the ambulance. She sees the paramedic shake their head as the ambulance doors close.
Skip ahead two years and much to Charlottes surprise, her new real estate client is non other than the woman who hand she held as she died. Except that she apparently didn’t die! That moment 2 years ago had such a profound effect on Charlottes life. She is thrilled to find out that this woman, whom she felt immediately drawn to that day on the bus is alive.
Marin, is also surprised and happy to see that Charlotte is her realtor. She has thought about the kind woman who held her hand that awful day that altered the course of her life.
The two form a quick friendship. The connection they both felt on the bus is still very much there. But is there more to it than just friendship? Is there a growing attraction between the two women?
What first drew me to this book was that the word mystery was in the description and house hunting. I don’t read many (okay it’s been years) romance centered books anymore and have been wanting to slowly dip a toe back into the genre. I remembered liking books by this author years ago and decided to give this book a try.
It was a cute story two women’s journey in finding themselves. Finding their authentic self. I am often envious of small children because they seem so purely authentic. When does that change? And why is it so hard to be our true selves? I suppose for some people, they don’t know their true selves so it does become a journey to find that. For others, they may know, but are afraid to let others know. As for the rest, I am fresh out of ideas! It could be so many things that factor in. Lucky are those who are their true authentic selves.
Both women are experiencing changes in their lives when they meet again. Charlotte has decided to dig into search for her mom who went missing 30 years ago and work on getting to know her dad again.
Marin is newly divorced, recovering from her injuries and deciding that she needs to finally live for herself. She begins a new career and adopts an ADORABLE puppy, Ember. Bless that puppy’s heart. I think I need a dog friend. Is that weird? Is that a thing? Can I just borrow a friends dog for bits of time. Kind of rude to ask the friend to stay at home though, I suppose! 😂. I don’t know that I would be a good pet owner, that seems like a lot of pressure and work, but a dog friend to keep me company sometimes? I might like that. Of course it has to be a dog that I am not scared of! (Side note: I never had pets growing up due to a sister with severe animal fur allergies. And I also recently learned of an event that happened with a dog when I was apparently too young to remember it. I always had a specific incident in mind as to why I am afraid of most dogs, not all, but most, but there was an incident well before that too.) Anyways, back to Marin; She has also decided to ‘come out’ to her siblings.
I enjoyed this book. I have never read a f/f romance novel. I liked the day to day of their lives unfolding in front of me. How their friendship and connection evolved. And for those of you who like a steamy, tension filled, build up to romance…..there is definitely some of that in here!! Had I been reading this while other people were around, I would have maybe needed to stop for fear of possible blushing😂. It’s been a long time since I read a book with so much sexual tension in it!
I also need to mention that I loved how the main characters were 40 and 47. When I used to read romance books the mc’s were usually much younger. And now that I am in my early 40’s I really appreciate having a romance feature people closer to my own age. It was refreshing in a way.
Fate brought them back together. But can it keep them together?
I wasn’t a huge fan of the ending. I don’t think it was necessary to throw some of that back in, I think it took away from an earlier moment that would have maybe been more impactful without that extra bit. But that could just be me.
Overall a good book to get back into the romance genre!
Many thanks to NetGalley and Montlake publishing for this early digital arc of this book. All thoughts are my own.

There is a lot going on in this book. It has drama at the start in an awful accident for Marin, witnessed by a fellow commuting stranger, Charlotte.
Fastforward two years later Marin gets divorced, moves state/house, gets a new job in a college town, discovers she is a lesbian and then gets a puppy.
Charlotte moves back to her college town home, becomes friends with Marin, reaquaints with her estranged father and decides to unravel the mystery of her mums' disappearance twenty years ago. And then she also has a sexual awakening.
The author does a really good job of keeping many 'plot plates' spinning and characters together.
I felt at times the puppy - Ember was the needed cement to the story.
I loved Marin's character and her development. Charlotte was a bit frustrating sometimes. Having read Learning Curves it was also good to bring in their characters. More late drama was unexpected too.
Once I got into the tempo and plot shifts of the book I did really enjoy it.

Did I love this book? You better believe it! So much so that I signed up for an ALC when I wasn’t even halfway through the ARC and immediately started listening after I finished the book! I have absolutely no regrets! 😁
This story had all the vibes I usually fall in love with in Rachel’s books - a sweet tender romance that warms your heart, pining and spice that will have you fanning yourself, wonderful characters that feel like family, and queer joy galore. But this book also explored some different themes that we need more of in sapphic romance! Both Charlotte and Marin come out later in life and they both have incredibly unique journeys. I honestly don’t know if I’ve read another sapphic story where BOTH the MCs were older and coming out and experiencing their first time being with a woman. That part of the story was honestly one of my favorite things…watching them navigate this together was heartwarming and endearing and a joy to witness.
And I haven’t even talked about that prologue! OMG! My heart broke even though I knew everything wasn’t as it seemed in that moment. You’ve got Charlotte, avid horoscope reader, and Marin, the skeptic. There’s connection and you just know something is sparking between them, but then there’s an accident. TWO YEARS go by with Charlotte thinking Marin (whose name she doesn’t even know) is dead only to open the door to her new client and see her standing there, alive and well. 🤯 For two years both women could not get the other out of their heads, but fate decides to give them another chance. Except Marin is attracted to Charlotte and Charlotte is straight…right?
Marin is newly divorced, newly out as a lesbian, and looking to start fresh in basically every facet of her life - job, location, everything. Charlotte, also fresh off a breakup and trying to find her way in life, returned home to try to find out what actually happened to her mom when she disappeared during Charlotte’s childhood. They both have a lot going on in their lives and forge an immediate friendship that feels anything but new. Their chemistry is undeniable, even when they are both trying to deny it lol. You can see how much they care for each other - and ugh! The way Charlotte shows up for Marin with her chronic pain struggles and helping with the puppy and everything - to be cared for like that! 😭 But Marin’s speech at the end…just as powerful! Had me in tears.
And EMBER!! Oh my gosh I love that little dog. Truly a spotlight stealer in all the best ways. But the impact Ember has on Marin is absolutely beautiful. And I love that her favorite toy is the purple dragon! 🥹
I loved getting to see more of Audrey and Michelle from Learning Curves, too! The books are both standalones but set in the same world/university town in Vermont, and it made my heart happy to see the two of them still in love and thriving! Plus, I can’t not mention the Stars Collide easter eggs! Edanna Forever!!
And the narration! QUINN RILEY IS UTTERLY FANTASTIC!! If you have not listened to an audiobook narrated by Quinn yet you are missing out! Listening to this right after reading it made her narration that much more powerful. The way she captures all these incredibly emotional moments - the pain, the anguish, the longing, the fear, the desire. Sheer perfection. I have no words. I felt pulled into the story even more deeply than I did while reading. Between Rachel’s writing and Quinn’s narrating, I could feel every emotion as though it were my own. Quinn doesn’t narrate stories, she elevates them, brings them life, makes them tangible. Truly one of the greats! And these two make quite the dynamic duo!
I could go on, but I’ll leave it there for now. Beautiful romance. Intriguing storyline. Captivating characters. Incredible narration.
I received an ARC and ALC through the author, NetGalley, Montlake, and Brilliance Audio. This is my honest and voluntary review.

They both have a lot going on in their lives and forge an immediate friendship that feels anything but new. Their chemistry is undeniable, even when they are both trying to deny it lol. You can see how much they care for each other - and ugh! The way Charlotte shows up for Marin with her chronic pain struggles and helping with the puppy and everything - to be cared for like that! 😭 But Marin’s speech at the end…just as powerful! Had me in tears.
And EMBER!! Oh my gosh I love that little dog. Truly a spotlight stealer in all the best ways. But the impact Ember has on Marin is absolutely beautiful. And I love that her favorite toy is the purple dragon! 🥹
I loved getting to see more of Audrey and Michelle from Learning Curves, too! The books are both standalones but set in the same world/university town in Vermont, and it made my heart happy to see the two of them still in love and thriving! Plus, I can’t not mention the Stars Collide easter eggs! Edanna Forever!!
And the narration! QUINN RILEY IS UTTERLY FANTASTIC!! If you have not listened to an audiobook narrated by Quinn yet you are missing out! Listening to this right after reading it made her narration that much more powerful. The way she captures all these incredibly emotional moments - the pain, the anguish, the longing, the fear, the desire. Sheer perfection. I have no words. I felt pulled into the story even more deeply than I did while reading. Between Rachel’s writing and Quinn’s narrating, I could feel every emotion as though it were my own. Quinn doesn’t narrate stories, she elevates them, brings them life, makes them tangible. Truly one of the greats! And these two make quite the dynamic duo!
I could go on, but I’ll leave it there for now. Beautiful romance. Intriguing storyline. Captivating characters. Incredible narration.

4.5 ⭐️Thank you Rachel Lacey and NetGalley for the ARC! I am not sure why I am surprised that I loved this from the very beginning. I remember looking down at how far I was into the book and I was only 9% through when I literally said out loud, “This is so good.” I loved that Michelle and Audrey made appearances and I loved that Eden Sands was mentioned from Rachel’s other books!
Both MCs are over 40(40 and 47). I thought I might have an issue with relating to them due to this, but that wasn’t an issue at all. The way that Rachel writes her characters makes it so easy to relate to. They are always complex, dimensional characters and Margin of Error is no exception. Exploring the complexities of coming out later in life was realistic and I believe will help a lot of people. The fears, hopes, emotions of these two women were so visceral and well written, that you could feel it coming off the page
I can’t really say the way they met was a meet cute, seeing that Marin almost died right after, but it was unique the way they met and it tied up nicely with the plot and the ending. I was so interested in the missing mom portion of the story. Once again, a unique storyline that kept my attention. Yeah, this is a love story, but it’s so much more!

Rachel Lacey is doing some kind of sorcery because I absolutely fly through her books. I don’t want to say too much before this one is out but the plot is rich beyond the romance storyline and I absolutely loved the two MCs discovering things together—I haven’t seen that done before (not that it hasn’t , just not in a book I’ve read). Also, hooray for older heroines!

Love me a story with adult sapphics!! Both MCs are in their 40s and busy with their grown up lives and I enjoy that!
The start of this is so good, I was really hooked on this seemingly fated connection between Marin and Charlotte and really hyped to see their story unfold.
I like them and I liked the writing, but I don’t like the finding charlottes mom plot very much, especially in the middle part of the book where I felt like we should’ve been focusing on charlottes journey with her identity and Marins coming out and dating process.. it was just an unwelcome distraction tbh😅😅
Other than that I really enjoyed reading it and give it a solid 3.5✨

this one was fine. i don't love using that word but it does rlly kinda capture my feelings abt it. rachel lacey has written some fantastic sapphic books and this is one that i didn't rlly connect with as much. i liked both of the main characters, and i enjoyed their dynamic, but i think some of their conversations felt a little repetative for me? some of the narrative on marian FINALLY being able to be openly a lesbian and kiss a woman and have sex with a woman, got a little old, for me. it was just in her inner narrative a lot and they were also talking abt it constantly. i also don't care enough abt dogs to be invested in her puppy, unfortunetly. it was by no means a bad book and i would actually rec it, but it's not going among my favs by rachel lacey. i might also be suffering from a bit of a reading slump, and that might be coloring my impressions of it, as well.

I am enjoying these stories around Northshire University. Vermont is sounding very pretty in the two stories I’ve read here the stories are set.
In Margin of Error there’s more angst, more suspense compared to the first story. Unlike the first book, this one does not revolve solely around the University but instead involves the surrounding areas.
The sapphic pining and longing was intense. Both characters on their first sapphic experience and the difference in stages of acceptance was stark and beautiful to dissect.

Rachel Lacey had me at Chapter One with this story! A very clever way to pull the reader in and invest in this romance about fate and finding love where you least expect it.
Marin is a statistician in her mid-40s living a unfulfilling life in New York. She meets Charlotte, a realtor also commuting by bus to Manhattan from Queens, when she casually compliments her scarf. They strike up a conversation, and their brief interaction sparks a connection that surprises them both. That momentous meeting will profoundly change the course of their lives forever.
Margin is primarily set in the same idyllic universe as Learning Curve, Middleton Vermont. I hope this isn’t the last of them!
Fans of Lacey’s work will enjoy the Easter eggs sprinkled throughout.
I enjoyed the book very much and am anxious to hear narrator Quinn Riley’s performance of it!

(rounded up from 4.5)
I usually enjoy Rachel Lacey's books and rate them four-ish stars so it was no surprise that I also enjoyed this one but I feel it merits a bit of a special status just because of the sensitive and grounded approach to the subject matter: two late in life queer women coming to terms with their sexualities, attraction to each other, and other life things that inevitably come up.
Marin and Charlotte briefly interact on a shared bus ride because a horrible accident leaves Charlotte thinking that Marin died, and Marin has no way to find the unnamed stranger. Two years later, they happen upon each other again and strike up a friendship based on the shared trauma from that horrible day.
I enjoyed that with these two older women, we have two common approaches to late in life queerness. Marin has always pushed down her interest in women due to compulsive heterosexuality and now, after a life-threatening accident, is ready to live authentically. She reads sapphic romances and is intimidated by the idea of dating women when she is so late to the coming-out party and has no practical experience with women. Charlotte reacted to the accident by deciding to change her life and follow on paths that she could have persued to have no regrets and is now chasing up the biggest mystery in her life: where did her mother disappear to one evening as she left to go to book club and was never heard from again? It is truly the most inconvenient time for Charlotte to find she kind of has feelings about her new bestie, Marin, and it leads her to examine how straight she really has been and how much of her pansexuality she's ignored or not recognised all her life.
Lacey excels at capturing the "quiet" hurdles of coming out: the awkwardness of updating friends and family, the terror of dating a new gender for the first time, and the slow, often shaky strides toward self-confidence. It eschews melodrama for reality, focusing on the bravery required to take a chance on someone when you’re still figuring yourself out.
This is likely going to be what I'd recommend to anyone who was coming out as queer in their forties as an excellent guide to this situation and to make them feel seen and understood.

Nice, fun, easy read. Charlotte meets a woman while commuting and witnesses a very tragic incident. Two years later, Charlotte and Marin meet again, become good friends, and eventually form a romance.
I'm a huge fan of Rachel Lacey’s writing, so I came in with high expectations, and they were mostly met. The prologue really hooked me, so the story started very strongly. However, as things progressed, it kind of died down until the last couple of chapters, when it picked back up.
Overall, this is a solid romance with some very spicy scenes, emotional moments, action, and a little mystery. There were a few eyeroll moments, but I still really enjoyed my time reading it.

The start of Margin of Error was quite captivating and had me thinking a series of follow ups, and what really followed suprised me again, but then the middle of it was somehow much quieter and I found myself losing a bit interest, until the end where fireworks went on again, rushing towards the end.
Many know that I usually prefer a novel with much more angst. This one has some of it, and I think that some of my friends will really like it.
Not my fav by R. Lacey, but still and interesting reading.
There was a lot of crying involved. Both characters have past trauma and are highly emotional about intense events. Glad for the therapy recs for them.
Again... the start was like "Ohhhh god.. now what?!"
3.8 stars for me.
I relived the horror of potty training my dog while reading it. lol.

Just finished reading *Margin of Error* by Rachel Lacey (huge thanks to Rachel and NetGalley for the ARC!). The story follows both Charlotte and Marin as they discover their sexuality, which felt really authentic and made me think of my own coming-out journey. The nervousness, curiosity, and tenderness they experience came across as real and relatable.
Alongside that, there’s a gripping mystery about Charlotte trying to uncover what happened to her mom. Both storylines are emotional and well-written, with a satisfying ending to the mystery.
The writing is very detailed, which I usually enjoy, but here it sometimes slowed the pace and interrupted the flow. The style isn’t my absolute favorite but definitely enjoyable.
The start felt a little slow, but once the “gay panic” moments kicked in, things got way more interesting. I liked the couple, but their chemistry didn’t totally sweep me off my feet. Their love story was still sweet and cute enough to keep me hooked.
All in all, *Margin of Error* is an emotional, heartfelt story about self-discovery and family secrets.

General thoughts…
I absolutely loved Learning Curves, so I was looking forward to starting Margin of Error! Once again, I am notorious for not reading blurbs. But I knew I loved the first, so I knew I’d want to dive into this one too. Because I didn’t read the blurb, I ended up pleasantly surprised by this book!
Some things I loved…
- The older MCs! It’s less common to see, so when I do see it I’m drawn in. (And the MCs acted their age!)
- This book also includes some heavier elements like the disappearance of Charlotte’s mom. These aspects were approached in a way that felt realistic without being overdramatized.
- I thought the representation of Marin as a late bloomer lesbian (and as a divorcee) was really well done, and I think it will resonate well with others that have lived similar experiences or are going through it now. It’s something I loved to see in sapphic romances and would like to see more of.
- Then add in Charlotte’s sapphic awakening… I loved to see it. It felt like something that’s rarely seen in sapphic romances, and I was so happy to see their story unfold.
- I thought being able to see a variety of coming out experiences was great, since it can look very different.
- It’s always great to see characters from the previous book!!
Some things to consider…
- This book has a very different “feel” to Learning Curves. Charlotte and Marin’s love story is definitely unique to them and not overly comparable to Audrey and Michelle’s. If you’re looking for that same vibe, Margin of Error might not hit the way you expect it to.
- Stay away if you don’t like adorable puppies in your romance books.
- This book is lighter on the spice overall compared to Learning Curves.
Final thoughts…
I thoroughly enjoyed this book! This romance read so cozy and genuine. The characters felt so special, and I was so happy to be able to read their love story. Margin of Error fills a gap that is often missing in sapphic romance, and I thought it was handled well. Truly a special book.

After reading mixed reviews, I am happy say I’m in the favorable side. I liked the realistic characters in this story. Especially Marin who I could relate to. The darker plots of this book made it more interesting to me, instead of just a straight romance.

Margin of Error is the epitome of “never judge a book by its cover” or by its author, for that matter! While Rachel Lacey never disappoints when it comes to warm and cute Vermont vibes, this book definitely kicks it up a notch and isn’t like anything she’s ever written before!
Right from the start you’re sucked into the story with suspense and drama that will have you on the edge of your seat. All I can say is buckle up, it’s an emotional roller coaster. This is the first wlw book I’ve read with not just one, but TWO characters that have sapphic awakenings later in life- which was incredibly endearing and outrageously hot! Marin and Charlotte have such a delicate yet fierce love story that I’ll never get over, nor do I want to. And the puppy fever?? Little Ember stole my heart and used it as a chew toy!
Lacey never ceases to make me want to drop everything in my life, relocate to Vermont, and take on the fun hobbies her characters are up to. Lastly, the cameos from Learning Curves were carefully crafted and so important to the story, I cherished every minute. It made me want to reread LC again, however, I fear Margin of Error is now my new favorite by Rachel Lacey. It’s truly a book that is “1 in 8 billion”! Thank you so much Rachel Lacey and NetGalley for the ALC!

Really enjoyed this! Up until the last 80% where it just felt so rushed. I haven’t read anything where there was two MCs figuring themselves out later in life, really good premise and I was definitely hooked after the first chapter, but yeh the last few chapters let it down for sure
October 16, 2025
Rachel Lacey has been on my radar for a while, but I was a little hesitant to try her books because, generally speaking, I seldom connect with contemporary sapphic romance novels. Still, I was hopeful that I would enjoy this book—and Rachel's work overall—because of the hype surrounding her other titles. As I'm sure you can tell based on the 1-star rating, I did not.
I do want to start by highlighting the things I thought this book did well, which include having a lesbian MC who regularly uses the word "lesbian" to describe herself; having two MCs in their 40s; and discussing somewhat difficult topics like chronic pain, coming out, homophobia, and . Unfortunately, none of that was enough to overpower my dislike of the writing style or complete lack of interest in the plot. The writing itself was extremely casual and simplistic, and I didn't resonate with the humor or care for the pop culture references. It always drives me nuts when authors feel the need to spell everything out for readers rather than trusting them to make inferences and understand things that aren't explicitly stated, and that was the case throughout this book. As for the plot, I think this book suffered from trying to do too much at once. There was the main storyline involving Marin and Charlotte's developing relationship, and most of the smaller plot points directly related to Marin's experiences with starting over post-divorce and moving to Vermont, the totality of which seemed a little too busy for such a short book but also made sense thematically. On top of all of those things, however, there was also a storyline focused on Charlotte reconnecting with her dad and seeking answers about her mom, who disappeared when Charlotte was a child. It felt out of place amongst everything else and was also a bit odd to read about because it only came up a few times and then had a somewhat rushed and coincidental conclusion right at the end of the book.
Anyway, didn't love this. I struggled to care about the MCs, especially Charlotte, or their relationship much and was consistently put off by the writing style and quality. But, if you're more of a contemporary romance reader than I am and enjoy easy, somewhat corny reads, YMMV.

Review of advance copy received from Netgalley
The narrative follows the dual perspectives of Marin and Charlotte as they both find themselves falling for a woman for the first time ✨️
After a bad accident, Marin is embracing a second chance at life. With a new job teaching statistics at a university and a new home in Vermont, she’s ready for a fresh start — including exploring her sexuality. I loved this narrative: Marin, at 47, joyfully embracing life and wanting a girlfriend for the first time. Her excitement is infectious. Watching her join a dating app and put herself out there is light, fun, and genuinely heart-warming.
Charlotte has also recently moved and is drawn into a mystery involving her mother. Her growing friendship with Marin leads her to question her own sexuality, and their dynamic is warm, fun, and wonderfully developed. I loved the steady way the author shows Charlotte’s realisation that she’s interested in Marin — and when she starts finding statistics hot, you know she’s got it baaaaad 🫠
The slow build suits where both characters are emotionally, making the romance feel earned. The chemistry and spice are ⚡️ and sensual, before the story picks up pace. There’s some major drama towards the end that I didn’t see coming. I also really appreciated the inclusion of chronic pain representation, and it was a joy catching up with Audrey and Michelle from 'Learning Curves' 😍
Thinking back to Marin and her love of statistics, the odds of this romance ever happening felt low — neither woman ever imagined it. That’s what makes this such a lovely story about taking a chance ❤️

Thank you to NetGalley and Montlake for providing an arc in exchange for an honest review.
Margin of Error releases February 3, 2026
“Not everything can be explained by statistical models, even when you account for the margin of error. Sometimes, you have to trust your instincts and believe in the unbelievable.”
Two years ago, Charlotte’s life was altered when she stepped onto a bus and shared her daily horoscope with the woman sitting next to her, only to end up holding her hand as the woman laid dying on a sidewalk from a car crash.
Desperate for a sense of purpose, Charlotte has returned to her hometown in Vermont in search of answers as to why her mother vanished thirty years ago, but is caught off guard when her newest client as a realtor just so happens to be the woman from the bus whom she thought died.
Let’s start with the things I loved about this book. Marin’s character arc stole the show; I admired her strength in going out of her comfort zone, coming out later in life, and finding a second chance. Her chronic pain was also portrayed really well.
As for the romance, it definitely wasn’t the strongest considering the fact that Charlotte identified as straight for most of the story. At times, the bond between Charlotte and Marin felt more like transference due to the traumatic event they shared, rather than genuine attraction.
I would’ve loved if the reparation between Charlotte and her father had played a larger role in the story to balance out all of the scenes with the puppy.
Margin of Error is a companion novel to Learning Curves. While they can both be read as standalones, you’ll definitely appreciate the cameos of Audrey and Michelle more if you start with Learning Curves.

I love mentions of previous characters in the Rachel Lacey world! Especially Audrey and Michelle!! Always makes me smile. The goddam prologue had nearly sobbing! My god Quinn Riley nails it every single time!!
As someone who also has a chronic pain condition, this was hard. Not in a bad way, just in a touching way. It’s always nice to see yourself in books. Even in small ways. There was a part about 40% in that legit made me cry. And Quinn’s performance was perfection and just added to the pain and feelings. Gah! I’m gonna cry again writing this 😭 was just weirdly validating, you know?
I highly recommend this book and all of Rachel but my god this was good! Is it my new favourite Rachel Lacey book? Quite possibly!! It was so so good and had all of the drama and plot twists, I loved it (but also wanted to throw my book 🤣 in the best way I promise).
A little side note for little Ember!! What a sweetheart. I LOVE animals in books. Especially puppies 😍 she was such a cute edition and great for bringing the two MC’s closer together ❤️
Written in third person with 2x POV’s. Narrated by Quinn Riley. This book is also trope city and I’m here for it! Femme/Femme, Return to Hometown, Overcoming Trauma, Starting Over, Toaster Oven, Coming Out, Mature FMC’s, Slow Burn, One Bed and a Puppy! 3x Spicy Scenes (2 more with minimal description).

2.5 stars. This was... fine! It was cute and good. I'll always pick up new books by this author; she always delivers a solid read. But this one just didn't click with me beyond the surface level, and I found myself a little frustrated with the writing. This book made me feel like such a curmudgeon, because it was supposed to be emotional in a lot of ways that I recognised, but did not actually feel. I LOVE later in life coming out stories, but this was saccharine and a little overly sentimental. And I know, I know! It's a romance novel! Where do I get off calling it 'overly sentimental'? It's probably just as sentimental as it needs to be!
...Nevertheless, it didn't really click with me. I'm very much NOT a horoscope or astrology person, so when I realised that that was a through-line that would run all the way through the book, I couldn't stop rolling my eyes. Something about the style of dialogue really did not work. I kept thinking, 'No one talks like this. No one would say this in that way.' Everyone was often super literal. Again, I really liked the premise and the characters, and especially the very unorthodox and heat-wrenching meet-cute at the beginning. This is a late coming out for both of them, and I liked how the author handled it, especially for Marin, who was so eager and excited to live her lesbian truth. And the side-plot with Charlotte looking for her missing mother was definitely unique. But the way it was all written... I don't know. It lacked something.
Listened to the audiobook as read by Quinn Riley, which is a big part of why I picked this up in the first place. I love her voice! And she definitely delivered the best performance possible with the material she was given. But all in all... eh. This was good, but no more than that.
