It’s the beginning of the summer, and Nicola Carr has just arrived on Block Island, RI, eager for a fresh start and some R&R. But her plans for a tranquil summer are quickly derailed when she meets the neighbor who owns the mansion next door, Juliana George, an enigmatic entrepreneur with a past shrouded in mystery.

Juliana, CEO and founder of a hot fashion-tech company, is spending the summer on Block Island preparing for a major IPO. But she’s chasing her dreams in more ways than one. This summer she hopes to rekindle a flame with a man from her past—a man who has a surprising connection to her neighbor Nicola.

Taylor Buchanan, the wife of Nicola’s cousin, is second-in-command of a real estate empire. Her life is exactly the way she planned it, and there’s nothing she’ll let get in her way of Having It All. But when everything suddenly verges on the edge of collapse, she has no choice but to take matters into her own hands.

As Nicola, Juliana, and Taylor’s summers unfold, the three women are set on a collision course that leads to inevitable self-discovery, unforgivable betrayal, an unavoidable love triangle in this gripping domestic thriller—and, most unexpectedly, a dead body.
