A thousand years ago, a brutal warrior roamed the Russian steppes and struck a sinister bargain. In return for the ability to change at will into a coldhearted predator, Konstantine promised his soul—and the soul of his descendents—to the devil.
Then one day a dangerous prophecy reveals the truth: One family has been chosen to battle the darkness—or face damnation.
Ann Smith loves her dynamic boss, Jasha Wilder, but her daring plan to seduce him goes awry when she encounters a powerful wolf who, before her horrified eyes, changes into the man she adores. She soon discovers that she can't escape her destiny, for Jasha is Konstantine's descendant, and Ann is the woman fated to break the curse that binds his soul.
