Emma Memphis is sixteen, broke, and drowning under the weight of a broken family. Carter Reed is twenty-four, infinitely wealthy, and the most feared mafia monster in the city. Five years ago, Emma's brother died, leaving Carter with one rule: protect her from a distance. But when a diner shift turns into a bloodbath, Emma kills a rival boss in self-defense and runs to the only lifeline she has left. Now pinned to the floor by Carter's own oblivious guards, Emma's about to find out exactly what happens when you bring a ghost's promise straight to a monster's doorstep.
