To protect humans from evil yet remain undetected, the Fangborn follow strict rules—but werewolf Jack Parker just keeps breaking them. Failing to disclose his relationship with a Normal could cost him his powers, yet there’s something irresistible about waitress Emily Vargas. For one thing, she seems to have no past—at least not one she’ll talk about.

Jack has kept his affair from the Family but not from his partner, Sully. Lucky for Jack, Sully has more important things to do than report him—like the duo’s strange new assignment. An oracle is barricaded in the Tower of London, refusing to turn over a precious sword until Jack and Sully complete an unusual task. If they succeed, the oracle may reveal Emily’s secret. But if a little knowledge is a dangerous thing, too much can mean the difference between the future Jack longs for and a living hell.

Dana Cameron’s prequel novella brings new depth, richness, and intrigue to her acclaimed Fangborn series.
