Maggie Lee is not your average hitwoman. For one thing, she's never killed anyone. For another, after hitting her head in the car accident that killed her sister, her new best friend is a talking lizard—a picky eater, obsessed with Wheel of Fortune, that only Maggie can hear.

Maggie, who can barely take care of herself, is desperate to help her injured and orphaned niece get the best medical care possible, so she reluctantly accepts a mobster's lucrative job offer: major cash to kill his monstrous son-in-law.

Paired with Patrick Mulligan, a charming murder mentor (who happens to moonlight as a police detective), Maggie stumbles down her new career path, contending with self-doubt, three meddling aunts, a semi-psychic friend predicting her doom, and a day job she hates. Oh, and let's not forget about Paul Kowalski, the sexy beat cop who could throw her ass in jail if he finds out what she's up to.

Training has never been so complicated! And, this time, Maggie has to get the job done. Because if she doesn't . . . she's the mob's next target.
