With one of The Heroes of the Horde members kidnapped by the demons, the remaining five face an insurmountable obstacle: The most likely location of their missing friend is inside the demon realm. Without a clue how to enter--and, more importantly, how to get back out again--the team reaches a breaking point. With morale weakened, their relationships crumble and are tested further when a newcomer enters the group. Either this new member tears the group apart or holds the key to eradicating the Horde once and for all. Surprisingly, their superpowers continue to grow amidst the turmoil until a hundred-year-old mystery is unveiled...one that finally allows them to locate the leader of the demon Horde.
