Guardian of Cascadia — R.D. Brown

All Dean wanted to do was enjoy his anime and video games, not live in them. That is exactly what the teen has found himself doing though when he wakes up to find himself in a strange new land. This land seems like it came out of a manga. Dean's troubles do not end with simply being in a manga. It continues when he finds himself being the hero of one complete with being part of a prophecy and expected to vanquish an unknown evil.
