Ace, the werewolf world's most feared murderer. At age 18, he wiped out four packs- thousands of lives were lost that year. His murderous rage continued till one day where he caught by the top pack's alphas and thrown into the highest security prison to rot. Why give them the death penalty when they are on the verge of death for years, writhing in pain? Four years later a high school with a student named Lillian has to go to Security Prison Alpha for a mysterious school field trip that her pack set up. Warning: This story contains kinks, gore, and self-harm. This is a complete rewrite of my original Prison Mate, four years later.
