This Adventure Ends — Emma Mills

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 in love, 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 the most serious person Sloane's 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 takes her across state lines―and ever deeper into the twins' lives.

Filled with intense and important friendships, a wonderful warts-and-all family, shiveringly good romantic developments, and sharp, witty dialogue, this story is about finding the people you never knew you needed.
