We all have a monster living within. It is our choice whether to cage the beast or feed it. For Cory Cattson, this is a choice he will be forced to make, quite literally and quite soon. In the 2200s, nothing much has changed on Earth except for two notable differences: The citizens of the planet have successfully rallied to take better care of their home, and it is now an accepted fact that life does exist on other worlds-and it is not all friendly and benevolent. Cory is recruited to join a unique high school that trains Earth's protectors. He survived a brutal attack by an evil creature when he was a small child and still carries the scars. No one suspects that for Cory, the worst is yet to come. Within his body, his attacker planted a malevolent spirit, one that seeks to terrorize the universe. That the host must be sacrificed is a small price to pay. As if his childhood was not traumatic enough, Cory must now deal with the most terrifying adversary of his life: himself.
