The Ramshead Algorithm

Ramshead Jones has discovered a secret in his backyard: a portal inside the hedge maze that leads to a near-infinite number of realities. But his wealthy, dysfunctional family has their own maze of secrets, and when the hedge maze and the portal—and Ramshead’s only way out of his meaningless life on Earth—are threatened, Ramshead must confront his painful familial truths to harness the alien magic needed to save his planet’s future.
