The moment Cassi's gaze locks with Mercer Chaplin's she know she has to have him. She scoffs when her best friend warns her to stay away. But maybe she should listen. When her aunt comes to reclaim her for the legacy of Pandora to hunt down the evils released by her troublesome ancestor, Cassi rebels. She’s determined to get as much from her last year of college as possible, including Mercer. But he's got secrets of his own. And as she falls deeper down the rabbit hole, signs begin to suggest that Mercer could be one of those evils she's fated to hunt. Too bad Cassi can’t put her heart in a box.
