Bo is hired by a Dark Fae named Mayer to find out how a human managed to win a bet with him. The reward for finding out is having an Oracle reveal something of Bo's past to her. Bo solves the mystery by finding out that a Fae that can jump between human corpses, called a Hsien, managed the deed. In the end, the answers Bo seeks are not given, but she does learn one thing. Her mother is alive, and coming for Bo.

While tagging after Lauren and Bo in the Fae world, Kenzi becomes deathly ill (and incredibly grossed-out) when she inadvertently eats some toxic human soup at the home of an Aswang.

A murder-suicide leads a human household to hiring Kenzi as a Shaman. Accidentally cleansing their house, a psychosis-inducing venomous Fae spider tags along when she returns home.

Bo's freelance work earns her a lead on someone who might know something about her mother... but the trail ends at Lou Ann, a death row inmate who claims not to know anything at all. Desperate to prove otherwise, and increasingly convinced Lou Ann is innocent, Bo uses all her Fae connections to try and bust her out of jail. When she has to admit defeat, Bo's goal switches to one of personal vengeance: to find Vex, the Fae that framed Lou Ann, and make him pay.

In the wake of emotional losses, Trick reveals his deepest secret to Bo. Bo realizes there is no turning back and she must go to any extreme, which includes aligning herself with a sworn enemy, to take on a battle that could decide the fate of the Fae.
