After an abrupt end to her steady college relationship, Samar Karam is back at square one: Benjamin Butler. Her childhood friend, mortal enemy, neighbor, and ex-boyfriend all wrapped up in one, Ben is all but a permanent fixture in Samar's life, with only one goal: to get her to stop rejecting him. When Samar and Ben find themselves on vacation in Florida during winter break, with only a door separating their two hotel rooms, they quickly discover that the line between friend and foe is a lot blurrier than they once thought. And the line between love and hate? Almost nonexistent.
