For most, ghosts and monsters were fantasy. For Tessa Byrne-Reyes, they were a constant in her daily life as a reaper. The legendary gods and creatures of mythology were, to her, historical figures. From a young age, she carried the weight of the world on her shoulders, possessing what she saw as a curse but what her family considered a gift. It was her birthright, to use her abilities to guide the deceased to the afterlife of an eternity in peace or in torment.

Her classmates viewed her as "the fainting girl" who would pass out in the middle of a lesson with inexplicable injuries. She experienced each death in the town of Belmont Falls, from the mundane to the gruesome. A gunshot wound in the gut, broken ribs, her heart ceasing to beat for several minutes. No one understood what caused these incidents but over the years, she gained a reputation for being abnormal.

While Tessa is the freak of Belmont Falls, Fin Belmont, the charming rebel and son of the richest man in town, is her polar opposite. Knowing each other for years but never saying more than a dozen words between them, one night changes everything, thrusting them into each other's unfamiliar and daunting worlds. Together, with the help of her best friend/his ex-girlfriend Elena, they begin to unravel secrets about their town and their pasts, learning that some secrets are better left buried and grudges can be held for centuries.
