Discoveries: Book 1 in The Elemental Series

Sam's a 16 year old boy who loves to be out, about and doing something, and, unfortunately for him, he has to spend his summer vacation cooped up in his dad's stinky apartment.
From time to time, he manages to escape, but on one of these occasions, he dives headlong into a world he didn't even know existed, let alone that he belonged to it.
