Cassie never knew werewolves existed, until the night she survived a violent attack... and became one herself. After three years at the bottom of the pack, she'd learned to keep her head down and never, ever trust dominant males. But when she discovers wrongdoing in her pack, she has to go above her Alpha's head to ask for help. Then Levi Cronin, the enforcer—and son—of the leader of the North American werewolves, came into her life. His father has sent him to Jersey to clean up a problem there. Levi never expected to find Cassie, a rare Omega wolf - and he certainly never expected to recognize her as his mate. Cassie proves invaluable as she and Levi go on the hunt in search of a rogue werewolf—a creature bound in magic so dark that it could threaten all of the pack.

Three years ago, Sarah Laycon discovered that she was a witch. It's gotten her into a few scrapes. Her non-gifted mother has been as supportive as possible, consulting Sarah's estranged father—an elusive European warlock—only when necessary. But when Sarah attracts too much human attention for a prom-night spell gone horribly wrong, it's her dad who decides her punishment: exile to Grimme, an isolated reform school for wayward Prodigium, a.k.a. witches, faeries, and shapeshifters. By the end of her first day among fellow freak-teens, Sarah has quite a scorecard: three powerful enemies who look like supermodels, a futile crush on a gorgeous warlock, a creepy tag-along ghost, and a new roommate who happens to be the most hated person and only vampire student on campus. Worse, Sarah soon learns that a mysterious predator has been attacking students, and her only friend is the number-one suspect. As a series of blood-curdling mysteries starts to converge, Sarah prepares for the biggest threat of all: an ancient secret society determined to destroy all Prodigium, especially her.
