The Storm Runner - J. C. Cervantes

Zane would much rather explore the dormant volcano near his home in New Mexico than go to school with kids who bully him for his limp. But what Zane doesn't know is that the volcano is a gateway to another world, a world he's thrust into with his dog, Rosie, and the new girl at school, Brooks - kicking off an epic adventure full of surprising discoveries, dangerous secrets, and an all-out war between the gods. To survive, Zane will have to become the Storm Runner. But how can he run when he can't even walk well without a cane?
