A cloaked figure arrives in Ellishome, Colorado besieging the town in madness, murder, and evil. But as the people search for answers, Seth Auburn, an eleven-year-old boy, has some questions of his own, especially when Ben, a magical tiger, appears in his backyard. Ben and the stranger are linked, waging wars for centuries across the galaxies, and their most recent battle has brought them to Ellishome.
Seth can aid the tiger in destroying the stranger forever, but it's going to take more than courage and sacrifice. Seth is going to have to trust the tiger with his very own life. With a gang of newfound friends, Seth and his companions travel deep into the Rocky Mountains, where they meet ancient foes at every turn. A magical white edifice stands between the worlds of light and dark. But the quest for redemption lies in something far more magical.
