Two teenagers—an ex-social media star and girl who feels totally adrift—find an unexpected connection on a eleven-day, senior citizens cruise. But will rough waters sink their temporary love story?

Tate Hall needs a sign. At least, according to the fortune she finds in a trinket shop. Which makes sense, because lately she’s felt totally adrift. So when her grandma offers her a spot on a Mediterranean cruise during spring break, she jumps at the chance—even if the cruise is for senior citizens, not seniors in high school.

Running headfirst into Luca Park, ex–social media star and one of the only other teenagers on board? Definitely not a sign. Nor is the fact that Luca needs someone to help him film videos for his secret new channel, or that everything Tate shoots for him goes viral.

As they travel from port to stunning port, something between them starts to grow—just as the views on Luca’s videos skyrocket. Can their electric connection last beyond their eleven-day journey? Or do all signs point to the end of their love story before it can really set sail?
