The hunt is on! Sixteen-year-old Bree Sunderland must inject herself with an untested version of her father's gene therapy to become a werewolf in order to stop a corrupt group of mercenaries from creating a team of unstoppable lycanthrope soldiers. When Bree went with her scientist father to Ireland, she thought it would be a vacation to study bog bodies. She never expected to fall in love with a mysterious young Irishman and certainly never expected to become the kind of monster her father said only existed in nightmares. Dr. Sunderland discovers that lycanthropy was not a supernatural curse but rather a genetic mutation. When they return home, her dad continues his research, but the military wants to turn that research into a bio weapons program and rogue soldiers want to steal the research to turn themselves into unstoppable killing machines. Bree's boyfriend Liam surprises her with a visit to the United States, but there are darker surprises in store for both of them. As evil forces hunt those she loves, Bree must become an even more dangerous hunter to save them all.
