Ariel Dantes is running out of time. Her brother Armand has disappeared while investigating a secretive cult professing to be a coven of witches and warlocks. When the police won't agree to open a case, Ariel must track down the last man to see her brother—self-professed warlock Lucien Morgret.

Bar owner and banished warlock, Lucien will do anything to protect his former coven. His doubts about the coven's safety have been building, and now a journalist is missing. He'll help Ariel...as long as she obeys his rules.

If Lucien and Ariel want to save Armand and the coven, they need to work fast. With time against them, and a rogue warlock practicing the forbidden Old Ways, they're running out of options. Lucien realizes he will need to meld with Ariel's mind—and body—in order to fight the darkness. But will mating with this mortal woman save him or damn him? Will they lose themselves, and the ones they love, forever?
