A hilariously chaotic Valentine’s Day time loop, a grumpy-yet-sweet love interest, and one girl who has been living by the wrong checklist her entire life.

Meet Lynn Painter — the author who gets teen romance right

Before we talk about the book, you need to know who wrote it because it matters. Lynn Painter is not a debut author hoping for a lucky break. She is a #1 New York Times bestselling author with a growing library of rom-coms for both teens and adults, including Better Than the Movies, Betting on You, and Mr. Wrong Number.

Based in Omaha, Nebraska, Painter also writes as a community columnist for the Omaha World-Herald. That journalistic eye is visible in her writing she is precise, punchy, and never wastes a sentence. Her signature style blends warm humour with real emotional honesty, and she has a rare ability to write teenagers who actually sound like teenagers, not like adults pretending to be sixteen.

When a writer of this calibre turns her attention to a time-loop Valentine’s Day story, you sit up and pay attention. The Do-Over is proof she knows exactly what she is doing.

The Do-Over by Lynn Painter — what is this book actually about?

Emilie Hornby has the most important day of her life perfectly planned. The outfit is picked. The gift for her boyfriend Josh is wrapped. The three words “I love you” are rehearsed and ready. It is Valentine’s Day, and for once, everything is going to go exactly right.

Then it all falls apart spectacularly.

She crashes her van into the truck belonging to Nick Stark, her gruff and deeply unimpressed Chemistry lab partner. She loses her journalism fellowship placement due to a clerical error nobody warned her about. And in the cruelest twist she catches her boyfriend kissing his ex. By the time Emilie falls asleep at her grandmother’s house that night, she has nothing left to salvage.

Except when she wakes up, it is February 14th again.

What follows is a time-loop story with real stakes. Emilie keeps reliving the worst day of her life, and every attempt to correct it sends her crashing back to Nick Stark — who turns out to be considerably more complicated than the scowling boy she dismissed all year. The plot is tight, funny, and genuinely surprising in places. Painter never lets the loop feel repetitive, which for a book with this premise is no small achievement.

Characters you will actually care about

Emilie Hornby — the girl with the perfect plan

Emilie is a straight-A student who runs on checklists, plans three steps ahead, and even selected her boyfriend based on a list of ideal qualities. On paper, she is doing everything right. Under the surface, she is quietly terrified of making a choice that has not already been vetted and approved.

Her parents’ difficult divorce sits at the centre of this fear. It quietly shapes how she approaches love if you plan hard enough, nothing can blindside you. The time loop forces her to realise that this strategy has not been protecting her. It has been shrinking her. Emilie’s arc from anxious people-pleaser to someone willing to take a risk without a safety net is the genuine heart of this book, and it lands.

Nick Stark — grumpy on the outside, quietly devastating on the inside

Nick is introduced as the worst possible way to start a bad day the owner of the truck Emilie slides into on an icy road. He is sarcastic, blunt, and barely tolerant of her frantic apologies. Then he hands her his coat in the cold without being asked, and the dynamic shifts entirely.

Nick carries his own quiet pain. He is not performing the brooding routine for effect. There is something real and a little worn underneath the sharp edges, and the scenes where he and Emilie stop sparring long enough to actually talk are the best in the book. Their chemistry is not just electric it is healing. Two people recognising something in each other that neither has let themselves acknowledge.

The supporting cast

Grandma is the quiet MVP the safe harbour in Emilie’s storm, and the most grounded adult in the story. Josh, the “perfect” boyfriend, is handled with more nuance than the role usually gets. He is not a villain. He is just the wrong person, which is actually more painful to read. The friend group is warm and believable without stealing scenes they have no business stealing.

Themes that make this more than a fun rom-com

On the surface, The Do-Over is a hilarious Valentine’s Day loop story. One level down, it is something considerably more interesting.

The central question the book keeps asking is whether love can actually be planned and whether the obsessive planning was ever about love at all, or about control. Emilie’s checklists are a coping mechanism built on the rubble of her parents’ marriage. She does not want a boyfriend; she wants proof that if she does everything correctly, nothing will break. The time loop dismantles this theory gently but completely.

There is also an honest treatment of how divorce reshapes a teenager’s sense of financial and emotional security. It never becomes heavy-handed, but it gives the story a weight that keeps it from floating away into pure fantasy. The “Day of No Consequences” a chapter where Emilie finally stops optimising and just lives is the emotional pivot of the entire book and one of the most purely enjoyable sections of any YA romance we have read this year.

Lynn Painter’s writing — sharp, warm, and effortlessly readable

Every chapter opens with a short, italicised confession from Emilie something she has done that directly contradicts her good-girl image. They are funny, perfectly placed, and do more character work in three sentences than some novels manage in three chapters. It is a clever structural choice, and it pays off consistently.

Painter’s prose is clean, conversational, and fast. She does not over-describe. She trusts her dialogue to carry the weight, and her dialogue earns that trust especially between Emilie and Nick, whose banter has the rhythm of two people who are extremely annoying to be around because they are clearly made for each other.

The Taylor Swift references are generous and completely unashamed. There is a full playlist included at the back of the book. This will either delight you or leave you neutral. It will not bother you. Pop culture references are woven in rather than dropped, and Painter knows when to stop.

The pacing is exceptional. This is a 304-page book that reads like a 200-page book in the best possible way.
