In #1 New York Times-bestselling author Casey McQuiston's latest romantic comedy, two bisexual exes accidentally book the same European food and wine tour and challenge each other to a hookup competition to prove they're over each other - except they're definitely not.

Theo and Kit have been childhood best friends, crushes, lovers and, after a brutal breakup four years ago, estranged exes.

It’s not until Theo and Kit are trapped on board a tour bus that they discover that they’ve each had the same idea: to take their dream European food and wine tour – alone. And now they’re stuck with each other for three weeks of the most romantic sights and sensuous flavours of France, Spain, and Italy. But it’ll be fine. They’re absolutely over each other.

So, when Theo suggests a friendly wager to see who can sleep with their hot Italian tour guide first, Kit is game. In fact, why stop there? Why not a full-on European hookup competition?

But sometimes a taste of everything only makes you crave what you can’t have.
