Jacklyn Madison never expected to be attacked by a beast on an evening snack run. Add a rescue mission enacted by a trained regiment of teenaged warriors, and her night officially becomes just like a scene from one of her beloved comic books. Turns out, her parents were once members of the Order of the Key, gifted humans that protect humanity from creatures spilling through inter-dimensional rifts. Unable to control her newfound abilities, Jacklyn and her family rejoin the Order.

After an attack on their headquarters leaves Jacklyn questioning their leadership, Kyp--the boy who led her initial rescue--reveals a darker secret. The Order's leader may be corrupt, and Jacklyn's questions could put her family in danger. Drawn into the search for proof, Jacklyn must use her guts and magical brawn to protect her family, her friends, and herself from the monsters spilling from rifts, and those hiding within the Order.
