Master Of Obsidian

Chicago's vampire community faces a new threat in the form of a potent street drug called obsidian. If it spreads, the city's undead and living alike could be pulled into violence on a terrible scale. Gideon, a vampire who works to keep good and evil in balance, is determined to stop it, and he relies on Jesse Madding, his loyal human assistant and oldest friend. Their partnership is tested when Gideon is secretly dosed and turns his pent-up feelings on Jesse, forcing both men to rethink what they mean to each other. As they investigate, they must also navigate an unfamiliar relationship built on control and surrender, all while tracking down where the drug comes from before it destroys them.
