Detective Jack Haney is tracking down the manufacturers of a new, dangerously toxic drug. He's disgusted to learn that her superiors have brought his former partner—and lover—Garrick O’Connel in to help with the case. The drug has a magical component that makes it hard to preserve, and Garrick’s magical abilities can get the job done. He seems eager to get back in Jack's good graces, but after the way they parted five years ago, Jack’s not sure he can trust Garrick. The case is turning deadly, and Jack's dangerous magic might be the only way to solve it. It also might kill him, but Garrick swears he can keep Jack safe while he hunts down the sorcerer behind it all. Can Jack trust him to keep his word this time? Can he trust Garrick to save not just Jack's body, but his heart?
