"It's far from business as usual when the body of a sister Fury washes up in Boston Harbor. But when Riss reports that the corpse's identity has been magically altered, she's immediately--and inexplicably--suspended from her job. Then a human assassin makes an attempt on her life, and Riss realizes that someone is trying to stir up strife between mortals and arcanes. When a Fury gets mad, she gets even, and Riss is determined to uncover the truth....

Riss has taken a leave of absence from the Boston PD to focus on her Fury duties, and becomes embroiled in a civil war which threatens to tear apart the Sisterhood and divide arcanekind.
