Sloane isn't expecting to fall in with a group of friends when she moves from New York to Florida -- especially not a group of friends so intense, so layered with private tragedies and secret codes, and so all-consuming. Yet that's exactly what happens. Sloane becomes closest to Vera, a social-media star who lights up any room, and Gabe, Vera's twin brother and most serious person Sloane has ever met. When a beloved painting by the twins' late mother goes missing, Sloane takes on the responsibility of tracking it down, a journey that crosses state lines -- and pulls her ever deeper into the twins' lives.
