Imagine you're an ordinary twelve year-old boy. The next thing you know, you're in the Seventh Mountain, an academy where students are trained as warriors, practical jokes are not just tolerated but encouraged, and the game of choice is a massive, four team version of capture the flag on horseback. Mark is a Magi- called to join others like himself to battle the evil of Benrah.
