"Utterly romantic." --Jenny Han, NYT bestselling author of To All the Boys I've Loved Before

The bestselling author of Windfall and The Statistical Probability of Love at First Sight returns with a meet-cute romance about Hugo and Mae, two teens who are thrown together on a cross-country train trip that will teach them about love, each other, and the futures they can build for themselves.

It's the perfect idea for a romantic week together: traveling across America by train.

But then Hugo's girlfriend dumps him. Her parting gift: the tickets for their long-planned last-hurrah-before-uni trip. Only, it's been booked under her name. Nontransferable, no exceptions.

Mae is still reeling from being rejected from USC's film school. When she stumbles across Hugo's ad for a replacement Margaret Campbell (her full name!), she's certain it's exactly the adventure she needs to shake off her disappointment and jump-start her next film.

A cross-country train trip with a complete stranger might not seem like the best idea. But to Mae and Hugo, both eager to escape their regular lives, it makes perfect sense. What starts as a convenient arrangement soon turns into something more. But when life outside the train catches up to them, can they find a way to keep their feelings for each other from getting derailed?
