Double Life - Book 1 of the Vaiya Series

Powerful rogue sorcerers who nobody believes exist, savage thieves who'll do anything for a little money, and corrupt pirates who terrorize the seas... None of these concerned Ian Hansen, a junior in high school, until one stormy night when a flash of lightning suddenly snatches him away to their world. Now, he's struggling to survive in this hostile world where one wrong step could be his last.
