White Witch, Black Curse

Confusion reigns for characters and readers in the complicated seventh urban fantasy outing (after 2008's The Outlaw Demon Wails ) for witch detective Rachel Morgan. Rachel's reputation is in tatters—to save humanity, she used powers that are considered evil—and she's still devastated by the mysterious death of her boyfriend six months earlier. Her attempts to solve his murder bleed into a case involving an emotion-sucking banshee, and soon Rachel has to bring in her PI partners—Ivy, a bisexual vampire, and Jenks, a pixie in existential crisis—along with empathic psychiatrist Ford and the banshee victim's father, Federal Inderland Bureau captain Edden. Harrison's unique vampire mythology unduly complicates world-building, and newcomers will be desperate for a glossary, but the nearly nonstop action nicely plays off the poignancy of Rachel's difficult life.
