Thanks to the ghosts who have been chained to her since birth, Maxi Cotter has given up on hoping for a normal life. The weirdness surrounding her keeps people away and has had her hopping from foster home to foster home her whole life. Her only goal is to increase the stash of cash meant to support her when she ages out of foster care, using the ghosts to do "impossible" tasks that her classmates pay for.

Maxi's solitary life changes when not one, but two people discover Maxi's secret and find it fascinating rather than frightening. Sheridan Daniels can detect the ghosts and insists that Maxi let her join some of her jobs to see them in action. Devin Courtney tangles his personal interest in Maxi with his need for her help. The three embark on a mission to find Devin's missing sister, Sydney. They uncover not just nefarious intentions at Sydney's school but a lonely, vengeful ghost who isn't about to let Maxi leave. Stopping the ghost means blowing up life as Maxi knows it…and possibly leaving her more alone than ever.
