Two best friends make a pact to lose their virginity on a school trip to Europe—if their feelings for each other don’t get in the way—in this shimmering, will-they-won’t-they young adult romance from the New York Times bestselling author of Today Tonight Tomorrow, Rachel Lynn Solomon.

August Levy and Reed Horowitz have always done everything together. Neighbors born a month apart, they were destined to be best friends, with August’s carefree chaos balanced by Reed’s gentle demeanor and occasional overthinking. It’s ridiculous, really, that everyone thinks they’re secretly pining for each other. They’d never let themselves be that cliché.

Now it’s senior year, and there’s one major milestone they’re hoping to hit before they start college: have sex for the first time. Their school spring break trip to Europe is the perfect opportunity, with no parents, considerable freedom, and the fact that both their crushes will be there. There’s just one snag: August has already lost her virginity, something she’s been keeping from Reed for reasons she can’t quite admit to herself.

From Paris to Amsterdam to Vienna, the trip pushes them together in unexpected ways, forcing them to confront long-buried feelings. They might be falling for each other in some of the most romantic places in the world—but what happens when vacation is over?
