Paradise with Your Nemesis
Let me set the scene: an entire wedding party has been felled by food poisoning. The bride is hugging a toilet. The groom is in similar distress. The seafood buffet - specifically the shellfish - has taken out every single guest. The only two people left standing are Olive Torres, the bride's perpetually unlucky twin sister who survived because she has a shellfish allergy, and Ethan Thomas, the groom's irritatingly perfect brother who survived because he considers buffets germ-ridden and refuses to eat from them on principle. And now there's a non-refundable Hawaiian honeymoon that someone really should use.
Olive and Ethan have disliked each other for years, ever since a disastrous first meeting at the Minnesota State Fair where Olive ordered cheese curds and Ethan made a face she interpreted as disgust at her eating habits. She's curvy, she's self-conscious about it, and she spent the next several years convinced that Ethan Thomas looked at her and saw a body to judge rather than a person to know. He's been cold and dismissive ever since - or at least that's how she's read every interaction. And now they're being shipped off to Maui together, where the resort thinks they're newlyweds and the universe clearly has a twisted sense of humor.
The Unhoneymooners by Christina Lauren - the pen name for writing duo Christina Hobbs and Lauren Billings - knows exactly what it is: a breezy, tropey, utterly delightful romantic comedy that delivers on every promise its premise makes. You know where it's going from page one. You don't care. The journey is the whole point, and this particular journey involves one bed in a honeymoon suite, a snorkeling trip where enemies end up holding hands underwater, and a near-naked collision in a tiny boat bathroom that neither of them will ever live down.
The Lucky Twin and the Unlucky One
Olive is convinced she was born under a bad sign. Her identical twin sister Ami - full name Amelia - wins everything. Contests, sweepstakes, radio call-ins: Ami enters compulsively and wins constantly, to the point where she financed her entire wedding through accumulated contest prizes. Her meet-cute with Dane (Ethan's brother) sounds like something out of a movie. Everything in Ami's life arranges itself with effortless grace. Meanwhile, Olive has been struck by lightning. She's had claw-machine incidents. She recently got laid off from her biotech job. The lucky twin / unlucky twin dynamic is played for comedy, but Christina Lauren gives it enough texture that it also reads as something real - the specific frustration of watching someone who shares your DNA move through the world as if the universe is on her side while you can't catch a break.
When the food poisoning strikes and Olive is one of two people still vertical, she wonders if this is finally her luck turning around. Then she realizes the other survivor is Ethan, and the comedy of the premise kicks into gear. Neither wants to be trapped in Hawaii with the person they like least in the world. But neither can afford to let a free luxury vacation go to waste - Olive especially, given her unemployment situation. And so the charade begins: they'll use Ami and Dane's reservation, pretend to be the honeymooners, share the suite (one bed), and somehow survive ten days in paradise without killing each other.
The Cheese Curds and What They Actually Meant
The miscommunication that fueled their years of hostility is the book's cleverest structural choice, because Christina Lauren doesn't reveal it all at once. We spend the first half of the book inside Olive's certainty that Ethan judged her at the State Fair - that the face he made at the cheese curds was a face about her body, her choices, her worth. Olive is biracial - white and Mexican - and her self-consciousness about how she's perceived, especially by someone as conventionally polished as Ethan, is woven into her narration without being heavy-handed. She doesn't just dislike Ethan. She dislikes what she thinks he sees when he looks at her.
The truth, when it surfaces - Ethan gets drunk enough in Hawaii to let it slip - is that his weird reaction at the State Fair had nothing to do with the cheese curds or Olive's body. Dane had told Ethan that Olive was off-limits, not to pursue her. Ethan's strange behavior was him pulling back from someone he was interested in, not judging someone he found lacking. Their entire multi-year hostility was built on a misread expression and an overprotective brother. It's a miscommunication trope, yes, and your tolerance for that device will shape your experience of the book. But Christina Lauren earns it by making the misunderstanding feel psychologically plausible rather than convenient - Olive's interpretation was wrong, but given her insecurities, it was the interpretation she was always going to reach.
Hawaii, the Boss, and the Ex
The Maui sequences are where the book is most purely fun. Christina Lauren lean into the vacation setting with obvious pleasure - snorkeling where Olive and Ethan are tethered together and end up holding hands, a paintball outing that turns competitive and flirtatious, boat trips with scenic views and that memorable bathroom collision, Ethan's confession that he's terrified of flying and carries a lucky penny. The forced-proximity mechanics are executed with the kind of attention to escalation that distinguishes good rom-com from lazy rom-com: every scene brings them slightly closer, every shared experience chips away at a wall they've both been maintaining.
The vacation is complicated by two unwelcome arrivals at the same resort. The first is Mr. Hamilton, Olive's new boss at the job she hasn't started yet - the one she got after being laid off. Olive panics and tells him she's on her honeymoon, which forces her and Ethan to maintain the newlywed act not just for the resort staff but for her future employer, a man who later reminds her that he hired her for her personal integrity. The second is Sophie, Ethan's ex-girlfriend, who left him with a note saying she didn't think they should get married after a three-year relationship. Sophie is at the resort with her new fiance, and her presence dredges up feelings Ethan hasn't fully processed. Both complications add stakes beyond the central romance - Olive's career is on the line, Ethan's emotional past is in the room - and they give the Hawaii section more dimension than a pure vacation-romance would have.
The Black Moment and What It Reveals
The book's major conflict arrives after they return from Hawaii, and it's sharper than the breezy first half prepares you for. Olive, Ethan, Ami, and Dane go on a double date. While Ethan is away from the table, Dane - Ethan's brother, Ami's husband - makes a pass at Olive. Not a subtle one. He suggests they swap partners. Olive is revolted and tells both Ethan and Ami what happened. Neither believes her. Ethan tells Olive that her refusal to accept his brother means they have to break up. Ami sides with Dane.
It's a genuinely painful sequence, and it works because Christina Lauren have spent the entire book establishing how important Ami is to Olive - the twin bond, the lucky/unlucky dynamic, the sisterhood underneath the comedy. Losing Ethan hurts. Losing Ami's trust hurts more. The black moment isn't just about the romantic relationship falling apart; it's about the family relationship fracturing, and that's what gives it real weight.
The resolution - Ami eventually discovers Dane's pattern of infidelity on her own, vindicating Olive - is satisfying without being surprising. Ethan's apology requires genuine reckoning with how quickly he dismissed Olive's word in favor of his brother's. The epilogue, set two years later with Olive and Ethan back in Maui, delivers the happy ending the genre demands: Ethan plans to propose but loses his nerve, and Olive proposes instead. It's a perfect character beat - the unlucky twin finally making her own luck - and it closes the book with exactly the right note of warmth.
What Keeps It at Four Stars
Here's the thing about romantic comedies: predictability is a feature, not a bug. We read them for the journey and the guaranteed happy ending, not for plot twists. The Unhoneymooners delivers on all of it - enemies who become lovers, forced proximity that creates intimacy, banter that becomes genuine connection. Christina Lauren execute these familiar elements with enough charm and self-awareness that the conventions feel affectionate rather than lazy.
What keeps it from five stars is the tonal unevenness around the Dane subplot. The book shifts from breezy vacation comedy to a genuinely dark betrayal (a married man propositioning his wife's sister, then being believed over her) in a way that the lighter first half doesn't fully prepare you for. The resolution of Dane and Ami's marriage - handled mostly off-page through a series of texts - feels rushed relative to the weight of what happened. And while Ethan's failure to believe Olive is addressed, the speed of their reconciliation doesn't quite match the depth of the wound. He chose his brother's word over hers without hesitation, and the book doesn't sit with that betrayal long enough for the forgiveness to feel fully earned.
There are also moments where the representation of Olive's Mexican-American family feels less assured - particularly a scene involving older family members questioning a relative's sexuality that some readers found clumsy. Most readers have responded positively to Olive's characterization and the warmth of her extended family, but the occasional uneven note is worth mentioning.
None of which changes the fundamental experience of reading this book, which is pure pleasure. The banter crackles. The Hawaiian setting sparkles. The one-bed trope delivers exactly what it promises. Olive is an endearing, funny narrator whose bad luck and self-deprecation make her easy to root for. And the cheese-curds miscommunication, when it finally resolves, manages to be both predictable and satisfying - which is the highest compliment you can pay a romantic comedy.
Rating: 4.0/5 ⭐
Perfect for: Beach vacations, enemies-to-lovers fans, anyone who needs a guaranteed happy ending with their humor and doesn't mind knowing it's coming from page one.
Skip if: Miscommunication tropes frustrate you, tonal shifts from comedy to darker family drama feel jarring, or you want something with more literary depth.
