Chloe Saunders used to be a normal teenage girl - or so she thought. Then she learned the shocking truth - she is a walking science experiment. Genetically altered at birth by a sinister group of scientists known as the Edison Group, Chloe is an aberration - a powerful necromancer who can see ghosts and even raise the dead, often with terrifying consequences. Even worse, her growing powers have made her a threat to the surviving members of the Edison Group, who have decided it's time to end their experiment - permanently . . . Now Chloe is running for her life with three other supernatural teenagers - a charming sorcerer, a troubled werewolf and a temperamental young witch. Together they have a chance for freedom - but can Chloe trust her new friends?
