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 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.

⭐️⭐️⭐️⭐️⭐️
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.

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.

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!

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.

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.

NetGalley provided this book to me as an ARC in exchange for my honest opinion. My first ARC!!!
This book was pretty cute, but there was a lot going on in it. I loved the characters and their growth, and their love story was very sweet. Charlotte and Marin each had their side stories going on as well, which were interesting and unique. Overall, I enjoyed the book.
That being said, this book was surprisingly intense. There were a couple of scenes that were intentionally shocking, but were much more in depth than I would have expected, given other aspects of the writing style. I wish I could say more about that, but I don’t want to spoil anything.
Margin of Error was also pretty repetitive. By the end of the novel, I found myself starting to speed read because I often felt like I already knew the gist of what some of the paragraphs were going to say. Some of the repetition felt intentional, perhaps to drive certain points/characteristics home, but some other repetition felt more like the author hasn’t been sure where to put a section and therefore put it in multiple places.
Another thing that bugged me was the level of detail. With events and settings, the details were vivid and often beautiful, but then the dialogue had a distinct lack of detail. In fact, the dialogue felt pretty stiff to me in ways that didn’t feel like they fit the characters.
I’m ultimately glad I read this book as my first ARC. It was a quick, cute, and easy read. 3.75 stars, rounded up

I absolutely adored this book. It was like the warmest winter hug, but still had moments of mystery, intrigue, and angst. Rachel Lacey’s writing is top tier. You can just feel all the emotions on every page.
Charlotte and Marin both had so much character development throughout this story and it was a beautiful story to watch unfold. Now this was a sloooow burn. Even slower than Learning Curves, so it was a bit of torture, but it was SO worth it. The yearning, the restraint, the tension.. it was perfect.
And Ember! The most adorable little side character ever! I love how a pet can add so much emotion and happiness to a story! The emotional stability and support that Ember provided for Marin was so heartwarming and I just fell in love with that puppy right along with them.
This was a late in life coming out mixed with a bi/pan awakening and these two characters shared so many firsts together, but Rachel wrote it all in the best way with so much care and understanding between them. I devoured this book in 24 hours. I finished it at 2 AM and I have no regrets.

Probably, because of my age and personal preferences (I definitely lean toward lighthearted, funny romcoms and I’m not a big fan of the friends-to-lovers trope), I’m not exactly the ideal reader for "Margin of Error". Still, I really enjoyed the atmosphere: the wintry setting, the cozy vibes, and the tender romantic tone of the love story!
The plot focuses strongly on the theme of coming out, and at times it reaches some very emotional and even dramatic moments. It’s not a topic that personally resonates with me, but I truly appreciated how sensitively and respectfully the author handled it, especially in showing how complex and deeply felt family dynamics can become during such a vulnerable time.
I liked both main characters: they have wonderful chemistry, and I think many readers over forty will especially relate to their quiet moments of mutual support and gentle understanding. The subplot about Charlotte’s missing mother doesn’t always blend seamlessly with the main storyline, but it does help keep the pacing lively in parts where the narrative otherwise feels a bit too slow. (Because cozy vibes are great, but we probably don’t need to know every detail about Marin’s puppy’s bathroom schedule or Charlotte’s daily breakfast, right?)
That said, the first meeting between the two MCs is absolutely thrilling: fast-paced, full of energy, and genuinely memorable. I also loved the ending; it felt emotionally satisfying and left me with a smile!
If you enjoy sapphic romances by authors like Melissa Brayden, Alexandria Bellefleur, or Clare Lydon, I’d definitely recommend giving this one a try!

Sapphic romances with mature leads are often a pleasure to read. For someone who is still young, reading about women who start over or discover themself despite being considered too old to do so (according to old society beliefs) is a source of joy and reassurance. Margin of Error perfectly reflects these experiences.
I found Marin and Charlotte’s first meeting memorable, and I enjoyed Charlotte’s approach to astrology. To follow Marin in her journey was such a pleasure; I found myself rooting for her each time she reached a new milestone.
Charlotte’s quest for answers was a hard one, and I liked how it conflicted with her discovering the nature of her feelings for Marin. I have to admit that I got a bit mad at her.
Ember made me swoon so much. She seemed so cute and sweet. The way she helped Marin warmed my heart.
It’s always cool to see characters from previous books, so I was happy to get some news from Audrey and Michelle, even if… well. You will have to read it to know.
Rachel Lacey keeps making me want to go to Vermont. The descriptions make me want to travel there without all the complications that come with going to the U.S.
Margin of Error is a great winter read if you’re looking for a story about starting over and finding love at an older age.

Thank you to the publisher for a gifted copy; all thoughts are my own!
📖 Book Review 📖 How many times in your life have you muttered the phrase, “What are the chances?” While you most likely do not know the probability, Marin is a statistic girl through and through but a near death experience has her risking it all for a second chance at her authentic life. Two years after an accident in Manhattan, she revamps her entire life in rural Vermont and starts afresh as a lesbian college professor.
What are the chances she comes face to face with the woman whose face was the last one she saw before nearly crossing over for good? For book stats, we’ll just say very unlikely. As Marin and Charlotte bond over their shared experience and get to know each other, their connection grows in an unexpected way that surprises both of them in the most beautiful fashion. Margin of Error is the cutest, not-at-all nerdy sapphic romance imaginable!

WOW. Margin of Error was more shocking and intense than I expected it to be. The characters go through some real stuff - BUT this is what brought me to love it so much! Seeing them go through these difficult things in life and learning more about themselves was inspiring.
Marin and Charlotte won my heart and I saw myself in both of them. Both are late blooming sapphics and their experience with that was written so well! Aaaaaaand friends to lovers is by far my favorite trope and it was so perfect in this book.
Overall, definitely recommend - and I’m so glad we got an update on Audrey and Michelle from Learning Curves, too!

This book is a perfect mix of sapphic romance, complicated pasts and discovering yourself. I loved how horoscopes and fate seemed to get in the way, resulting in this beautiful love story. Both main characters had a lot to accept and grow, and, most of all, learning how to do it together. It's a strangers to friends to lovers story, takes its time to build up, making it all make sense in the end. I really liked it and recommend to anyone who likes contemporary romance and women in love.

“You’re right that I’ve been running… hiding. I’m a total mess, but I want to be better.” “You can stop running now.”
❄️🐾🧣🚑☁️🏙️☕️🚨🏔️🪬📦🔑📊💼
I am so thankful that I received an ARC copy of Margin of Error and I am super grateful for Rachel Lacey for sending it my way!
Hopping into Marin & Charlotte’s story was really sweet. I must admit that this book was different from what I was expecting after reading Learning Curves. I wasn’t as invested in this love story as Learning Curves but it was still sweet. I love a good friends to lovers troupe and these two ladies are most certainly fated, written in the stars, destined to end up together. Reading Charlotte’s POV in the prologue had me so invested and I knew that we were in for a crazy ride.
“They smiled at each other, and that felt like a sign too. Of what, Charlotte wasn’t sure. But…Something.”
Trigger warning that should be addressed in Margin of Error - near death experience, PTSD, homophobia, internalized homophobia, traumatic accidents, and death/talk of death
In Margin of Error you have Charlotte Danton who just recently moved back to her hometown to solve the 30 year long mystery of her missing mother, reconnect with her father, and maybe find herself along the way. She is swearing off romance and partners after her last relationship with her boyfriend went up in flames. All of this came into place after watching someone die just 2 years ago and it changed her life… for the worse. Being back in Middleton she is remembering all of her bad memories and she just wants to keep them buried deep down but as she meets a new best friend, reconnects with people from her past, and is faced with some surprising truths she has to open MANY can of worms.
“New year, new Charlotte? The problem was, she’d tried out a “new Charlotte” so many times, she almost didn’t know who she was anymore.”
Marin Easterly is recently divorced, recently out as a lesbian, and recently employed at NU in Middleton she is starting over. She is finally living a life for herself at 47. She has waited over 20 years to be her true, authentic self. After a near death experience 2 years ago and a random blonde hair woman on the bus she chose to switch up her life and make a change. She is desperate for love, passion, and a life partner…with a woman. She wants to be open with who she is and stop letting her accident define her. She wants to adopt a puppy and find a wife and she is willing to do anything to make her dreams come true. But, she isn’t expecting to see the blonde haired woman in Middleton 2 years after this accident. She has to figure out how to keep those feelings quiet, just like she did for 20 years of her life.
“No more hiding. That's the promise I made myself when I left Andrew. I won’t apologize for who I am…”

Firstly, I want to say a huge ‘Thank you’ to Rachel Lacey for including me in your list of ARC readers, it’s truly an honour and I was so excited I almost cried when I got the email. Anyway, enough of that.
Secondly, holy crap! I devoured this book in 2 sittings, I just couldn’t get enough.
I had to read it twice, because I binged it so quickly.
Straight from the prologue I was ALL THE WAY IN! Horoscopes, chance meetings and then BOOM!
This heart warming story is about two women, Charlotte and Marin, who find each other again, 2 years after an accident that changed both their lives.
Charlotte, a Realtor by profession, has returned to her home town on a mission to finally know the truth about her Mother’s disappearance, by picking up the cold case on her own, and following wherever the investigation takes her.
Marin, newly divorced, is ready to come out and be her authentic self after her near death experience, and is navigating the road of recovery, a new career, AND a gorgeous little puppy whilst she’s at it. Talk about easing her in... Jesus.
She’s ready to start her new life, in search of passion, freedom and love, in the one place the beautiful stranger, obsessed with Horoscopes, told her about the day she almost lost everything.
I loved their dynamic straight away, Marin is honest, methodical and excited about her new life.
Charlotte, a serial escapist who runs from her problems instead of facing them head on, has a heart of gold and genuine interest in the lives of people she cares about.
This book had me by the heartstrings, and more than once had me grinning like an idiot, damn near in tears, and at one point... No spoilers... I fucking spat out my drink and almost fell off my chair. (IYKYK)
Also it’s lovely to see my Learning Curves beauties have a cameo in this book, still love Michelle and Audrey... But this story isn’t about you.
Rachel Lacey has done it again, and I know this will be one of my go-to reads, like many of her others.
Though this story covers some heavier themes of surviving trauma, family homophobia and the psychological toil of uncovering the truth,
Rachel manages to lace it all together (no pun intended) with humour, heart and an undying ability to make the reader feel safe, no matter what’s coming our way.
I always know, no matter what, Rachel’s worlds are a safe space... even if you did make me spit out my drink and panic-read the section over again!
*fans self*
I cannot wait for Quinn Riley to bring this book to life and make me ugly-cry all the tears all over again!

Firstly, I want to say a huge ‘Thank you’ to Rachel Lacey for including me in your list of ARC readers, it’s truly an honour and I was so excited I almost cried when I got the email. Anyway, enough of that.
Secondly, holy crap! I devoured this book in 2 sittings, I just couldn’t get enough.
I had to read it twice, because I binged it so quickly.
Straight from the prologue I was ALL THE WAY IN! Horoscopes, chance meetings and then BOOM!

📚Margin of Error
✍🏻Rachel Lacey
Blurb:
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.
My Thoughts:
This charming sapphic story is low angst but full of heart – perfect for someone looking for a cozy read on winter day.
Margin of Error drew me in at the prologue and kept me hooked for the entire read. This story follows Charlotte and Marin, both in their 40s as they are coming to terms with their sexuality and coming out later in life. This is a friends to lovers story where I really felt the emotions of both women. I was rooting for them as they became new friends and were drawn to each other. The addition of sweet puppy Ember to Marin’s life just added to the story. It was also fun to see Audrey and Michelle (from Learning Curves) again.
Thanks NetGalley, Montlake Publication and Author Rachel Lacey for the advanced copy of "Margin of Error" I am leaving my voluntary review in appreciation.

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
I had the chance of reading "Margin of Error" prior to its release, thank you Montlake & NetGalley for the ARC!
I gotta say, I went into this with high expectations. Winter vibes, an author who mostly writes wlw, older lesbians who seem cosmically destined to be a perfect match? On paper, this should have been exacly my kind of book. "I'm ready to fill my life with things I love" says our protagonist Marin at the beginning of the book and damn, so was I when I picked this up! Sadly, despite all the right ingredients, I didn't end up loving it though.
One thing that put me off quite early on was the dialogue, which at times feels like reading an interview between two people instead of natural conversations, mostly because the reader keeps being spoon-fed every single important information through it. It's also just plain awkward at times. Let's just say the one bed trope truly is one of my favs if done correctly, but if I ever have to read "Let's live out your 'only one bed trope'" in a conversation again, I will gauge my eyes out with the nearest sharp object.
And that's exactly where the book and I overall sadly ended up not getting along. I just don't vibe with the way it's written. It's mostly tell instead of show, rushed in some parts and then oddly drawn out in others. Furthermore, certain details about the characters and their backstories are reiterated so often that I got the impression the author assumed the reader might suffer from sudden memory loss if they weren’t mentioned every other chapter over and over again (or sometimes even talked about multiple times as if it was the first time each, which was quite confusing tbh), which ended up making them seem oddly stilted.
That said, the concept of the story itself is solid, the chemistry between the characters sweet (the puppy even sweeter), it's refreshing to read about an older pair of women finding out what they want from life, and I can absolutely see this working well for readers who enjoy a very direct and rather tell-y narrative style. It is not a bad book by any means, just sadly wasn’t for my personal taste as a reader, although I really wanted to love this one.

Rachel Lacey's books always have a way of pulling me into their vortex and enveloping me into their storyline, as her characters bob and weave through their myriad life experiences. Here ability to write believable dialogue is truly a gift!
Continuing in the location of the story from her previous book, Learning Curves, this story follows the chance meeting of two women on a bus in NYC and how their lives continue to impact each other as they move on from that impactful encounter two years later. I am not a fan of sharing spoilers since I like to read books without knowing too much about the characters lives and trajectory..so I'll tread lightly sharing the storyline....ignorance can truly be bliss).
This book centers around a small college town in Vermont where a woman from NYC moves to start a new job and begin a new life after her divorce. Another woman, also from NY, returns home to Vermont to reconnect with her dad after 20 years of having a distanced and awkward relationship. The storyline seems to write itself, if you know anything about relationship tropes, but there's so much more going on in this book and these women's histories. Like every one of us, we bring our personal histories to our friendships and relationships, especially as we get older and experience more life and loss. These experiences color and impact how we proceed with meeting new people, trusting strangers to become new friends, and then possibly moving on to something deeper.
Although some of the characters from her prior work make appearances in Margin of Error, this book is a stand-alone book (but if you haven't already read her prior works, please do!).
I was extremely lucky and thankful to have been provided an ARC of this book from the author and NetGalley and devoured it in no time at all. Once I started reading and connecting with the characters and storyline, I needed to know more.

I liked this novel a lot. There were multiple layers and subplots in addition to the romance which is something I always appreciate. Also, a puppy, who correctly got a LOT of screen time (the afterward said the author wrote this novel while having a new puppy themselves, and it SHOWS lol). This book did several unexpected things which is another thing which I always appreciate. There isn’t anything wrong with a formulaic sapphic romance novel (clearly I love them) but its always nice to enjoy your favorite thing with a slightly different flavor. This book is a hard-choice toss-up between a high 4 stars or a low 5 stars. Easily a 4.5 if I was able to give part marks.
Highlights:
-Starts with a BANG and certainly got my attention. It was also a neat initial premise that I enjoyed.
-I love a mystery subplot. This novel may not have spent a lot of time on the mystery or conducted it in a way that involved the reader (its not like there were clues we could put together) I still found myself reading along waiting to find out the answers.
-I love the rather meta idea of a character in a sapphic romance novel exploring their sexuality through sapphic romance novels.
-I loved following these protagonists as they rebuilt their lives; in far more ways than just romance.
-Double the “newly gay” vibes. You don’t often see that do you?
-This novel had excellent discussions about the complexities of coming out with your sexuality; at various ages and in various ways.
-Excellent communication…. At times.
Nitpicks:
-There was some very poor communication as well. There were decent reasons for it so I’m mostly giving this one a pass, but it was still a little frustrating at times.
-Note to readers: test your well water before drinking. Its not always good or safe, even if it tastes good.
-I wish there was more time spent on the second half of this novel, or the characters once they got together. Charlotte was worried about a lot of things that we never really got to see resolved (at least not in very much detail). I feel like the entire second half didn’t take its time in the way the first half did.

To say that I absolutely loved Margin of Error by Rachel Lacey would be a massive understatement. I particularly loved the fact that it featured two MCs in their 40s who were both going through the process of coming out, albeit at different stages along their self-discovery/coming out trajectories. It was also lovely to have the opportunity to meet two women who were experiencing their first same-sex relationship. Marin has known that she was attracted to women for a long time, but it took an accident almost claiming her life to prompt her to start pursuing the life she’d always wanted. Meanwhile, Charlotte has never knowingly been attracted to women but can’t help feeling the pull towards Marin, however innocently she may initially interpret their initial connection.
I also loved the fact that, while the story, mostly, was a gentle unveiling of their connection, there were still some heart-stopping moments that literally took my breath away.
Meanwhile the story clearly demonstrates the value in having support during the coming out process, irrespective of what age you are going through the process. I loved the way that Marin was able to support one of the students, even as she was still trying to work out how to come out to her family.
Margin of Error is a follow-on from Rachel Lacey’s previous release, Learning Curves although it could still be read as a stand-alone. That being said, Michelle and Audrey from Learning Curves do feature in this story so you may want to go back and read the earlier book first.

Rating: I'm between a 2.75 and a 3 stars for this one.
Review: I'm going to try to put my thoughts and feelings as best as possible without being mean. This was not my favorite sapphic romance and it was also my first Rachel Lacey book which does not bode well for me wanting to pick up her other books. I just felt like this story had to much in very little pages, we had the storyline of Charlotte and her wanting to find out what happened to her mother while also wanting to reconnect with her father while also just trying to figure out her sexuality. Then we had Marin who was dealing with the aftermath of a traumatic accident, divorcing, moving to a different state, having a new career, coming out and also getting a new pet for the first time in her life. There were so many things with our main characters that some of those things kinda were left in the air, Charlotte is presented as desperate to find out what happened to her mother but then there were like 5 chapters where that plot line was never mentioned or her father. Then we had Marin who was dealing with coming out to her family but we only got to see two family members reacting to that and then we never got to see if she repaired her relationship with one of her sisters. It just felt like the author put too many plot lines and tried to achieved it in under 300 pages. I also didn't feel the connection with Marin and Charlotte because for like the first 60% of the book she was straight and in her inner monologue you don't see any signals that she is feeling something non platonic towards Marin. It just didn't feel genuine and most of the time felt more and more of a trauma bond than anything. I would still recommend this book to someone who might enjoy it more.

This book was an overall charming read with a lot of moving parts. I really liked following the characters’ growth, and the romance had a genuinely sweet feel to it. I also appreciated that Charlotte and Marin had their own individual narratives alongside the main story—it added a nice layer of originality and kept things engaging. All in all, I did enjoy the experience.
That said, I was surprised by how intense certain scenes were. There are a couple of moments designed to shock the reader, and while I won’t go into detail to avoid spoilers, they went further than I expected from a story that otherwise feels light and cute on the surface.
I did notice a fair amount of repetition. By the later chapters, I found myself reading more quickly because several sections started to sound familiar, as if ideas or lines had been recycled rather than tightened. Some of it seemed deliberate for emphasis, but other parts felt like they could have been edited down.
The writing style itself had an interesting contrast—descriptions of settings and events were vivid and often quite beautiful, but the dialogue didn’t carry the same level of detail. Conversations occasionally felt a bit rigid, and at times they didn’t quite match the characters’ personalities.

Rachel Lacey is one of my favorite authors and after loving Learning Curves (one of my faves of the year), I was excited to pick up this companion novel. Set in the same town in Vermont but this time during winter. This starts out with a traumatizing event that I'm not usually expecting with contemporary romances. I think it set the tone for the book to be more emotional. I really enjoyed both Marin & Charlotte and their journeys and watching them fall in love. I am also a late in life lesbian, so I especially loved how this included a newly out woman and one who is realizing that maybe she isn't so straight after all. And this includes a first time... the steam was hot! There was a balance of trauma and overcoming what the characters go through and I felt that was beautiful how they lean on each other - it makes me happy these two met. I also liked the theme of living the life you want and just being happy. I did enjoy the cameos of Michelle and Audrey from Learning Curves & would totally love a bonus scene seeing how they all are doing 1-5 years later. While you don't need to read both or in order because of the cameos taking place after LC, I do recommend reading them in order (but it would still be fine if you read this first). I love her books and recommend this author.

After meeting Marin on a bus in New York, a meeting that ended disastrously when Marin was hit by a car just as she got off the bus, Charlotte escaped New York and returned to her childhood home in Vermont. Working as real estate agent she is stunned when her new client is none other than Marin.
After her accident, Marin's life changed in big ways. She realised she was a lesbian and ended her loveless marriage. She quit her job and decided to make the change complete she would leave New York and take up a teaching position at a small university in Vermont. But with scars and chronic pain she is taking things slowly.
As they look at houses, Marin fights her growing attraction to Charlotte who is straight. And for her part Charlotte is wondering if perhaps she is not as straight as she thought she was.
Margin for Error is primarily contemporary romance although with a mystery subplot in which Charlotte is trying to find out what happened to her mother who disappeared when she was a child. The sex scenes are quite steamy and honestly I flicked through those sections a little but I'm not lesbian, not even a woman so I'm not the target audience.
It's quite a sweet book and I enjoyed it despite the fact that it wasn't written for me.

Review of advance copy received from Author
It's easy to forget that coming out stories are important for adults too. It's also easy for those of us who are out to remember how hard it is to *come out*, over and over and over in the beginning. Rachel Lacey has done a beautiful thing here: She's given us two adults on two different coming out journeys. Marin has known she's gay for a long time, but compulsory heterosexuality pummeled her into submission, and she married a man she didn't love. Well, she's divorced and ready to come out to her family, be out in her new town and at her new job, and find love. And then there's Charlotte, who's only ever considered dating men — until Marin wanders into town looking for a real estate agent to help her find a new home, and flips Charlotte's heterosexuality on its head. It's actually the second time they've met; they experienced a tragedy together, as strangers, years earlier.
I had such an enormous fondness, and even protectiveness, over these two characters. I loved how exciting and scary and new and wonderful and harrowing every new step felt for Marin, and I loved how Charlotte just jumped in with both feet when she finally understood what was happening. This book took me right back to my own adult coming out like no book ever has. I wish this book had existed back then!

I’m going to keep it short, because contemporary romance isn’t my main genre, but I do love anything sapphic, so I decided to give it a shot. Take this review with a grain of salt, though.
The cover is pretty darn cute, love it. To get it out of the way first, I’m not sure of the quality of the steamy scenes since they are not my thing usually, but they looked pretty good to me. I did enjoy the chronic pain rep as well as the whole sexuality talk. There’s really nothing wrong with this book, and while I do have my gripes with it, it was cute and a quick, simple read, mostly dialogue.
Now for my problems with it. The main downfall of the book for me was that it was slightly boring. There wasn’t anything that captivated me, not even the characters (I couldn’t grow attached to them unfortunately) or the writing itself. The two main characters read the same (to me) (and so did the side characters, with the exception of the homophobic one), so it was actually really helpful that their names were mentioned a bunch. They also read quite young for their supposed ages. It felt more like a young adult book than an adult one because of it. Charlotte tells us multiple times how affected she was by her meeting with Marin, yet she forgets that Marin already mentioned her job on the bus when they first met (and that was a very important meeting, Char kept replying in her head, or so she says she did). There were quite a few pop culture references that date the book, but I get it, I suppose. Humor was not my cup of tea, but that’s different for everyone, of course. And the last thing is that the mystery around Charlotte’s mother was simply just alright, no high stakes, and I couldn’t bring myself to care much.
