In one of the most beautiful cities on Earth, following your dreams could become a nightmare.

Therese Hughes-Baldwin arrives in Boca Raton with hopes of joining the most prestigious dance company in South Florida. But instead of finding ballet success, she suffers an embarrassing heartbreak and takes a boring barista job. She also inadvertently gains the attention of the woman who stalks her on every train ride she takes.

So when Therese's favorite café customer, Dr. Dara Clemens, offers an escape to her beachside mansion, Therese can hardly say "yes" quickly enough. With her suitcase in hand and best friend Phoebe by her side, she heads to the Clemens' oceanfront getaway. The home is gorgeous. The beach is, too. So is the stranger Therese gives her number to at the bar.

But there are voices in the vents. And there are people who stare. And Therese faces a sinking feeling that something is hauntingly off about Phoebe's behavior. As Therese questions the motivations of those around her, she opens the door to a reality she never thought she'd find.
