Sisterhood, rather than romance, is the driving relationship of Kerri Maniscalco's Kingdom of the Wicked. Emilia and Vittoria are secret witches in Sicily, living quietly among non-magical humans. When Emilia finds her sister's body, she sets out to discover who killed her and get revenge. In her desperation, she turns to dark, forbidden magic, and the assistance of Wrath, a Prince of Hell, who claims to want to help her but has his own agenda.
