The end is near. Detective Danielle DeMarco is challenged with her most intense case yet, and along with it, she inherits a host of personal problems. When a sorcerer is found dead in The Emporium, a spell shop brimming with magical potions, elixirs, and tinctures, Dani and her new tagalong, Primrose, are on the case. However, work turns personal when someone close to Dani is poisoned. To make matters worse, another of Detective DeMarco's closest friends vanishes, her boyfriend is hiding something, and there is a new threat to the borough more dangerous than any in history. For Dani, it's no longer about simply wrapping up any single case. If she doesn't find out what's going on behind the scenes—and fast—there will be no more Wicked to defend.
