In an very old mega city overtaken by nature and decay, Kayn wakes up to a mystery—yesterday, it was winter, but today, it’s summer. More unsettling, he begins hearing a voice no one else can: Kourageous, an interdimensional being who pleads for his help to stop an alien force from finishing what they started long ago. Bestowing Kayn with cosmic powers, Kourageous prepares him for battle, but something disrupts their link, clouding Kayn’s mind and pushing him toward reckless decisions. In a world where he already feels like an outsider, Kayn must decide if he can trust his new abilities—or if he’s doomed to lose himself before the real fight even begins.
