A YouTubing cruiser couple sails the world living their best lives—until one of them goes missing and their whole world capsizes, in this captivating psychological thriller perfect for fans of Something in the Water and Saint X.

Sawyer Stone III and Dani Fox, a young couple who spend their time circumnavigating the globe aboard their 42-foot sailboat and documenting it for their fledgling YouTube channel Sailing with the Foxes, have anchored in Exuma, in the Bahamas. As they wait for the price of crypto to rebound so they can provision and continue their journey, they're partying and exploring with their fellow cruisers offshore. On the surface, everything looks perfect. But one night, Dani vanishes after a boat party, and Sawyer has no memory of her disappearance.

The search for Dani is initially fueled by concerns that she drowned during one of her daily ocean swims, but Dani's prescheduled video posts, recorded before she went missing, soon reveal a darker side to her relationship with Sawyer. Meanwhile, Royal Bahamas Police Force Inspector Veronique Knowles has her hands full trying to keep the investigation on course as the story of the American woman missing in the Bahamas goes viral and the internet sleuths unearth secrets from Sawyer's past. Sawyer Stone is far from perfect, but is he a murderer?

This twisty, edge-of-your-seat thriller will keep readers gripped all the way through the final satisfying turn.
