Fifteen-year-old Emmalynn Marie is the daughter of America's most wanted sorcerer, Tristan Atera. With the country out for the blood of magic, Emma has one hope to protect her identity: enroll in the Callistro Academy, an all-girls boarding school that once trained the secret agents hunting down her people. But any plans she and her best friends had for the school year quickly shatter when a pack of Grand Hunters finds Emma on the first day of school-and they suspect her for who she really is. As suspicions rise and the government closes in, Emma is thrown deeper into a war she is ultimately destined to fight in. She soon discovers that even her allies and greatest enemies have secrets just as fatal as her own, and she must protect her darkest secret before her family-and her people-pay the ultimate price.
