Mind Evolution - Clayton's Story: Mind Evolution Chronicles Book One

Clayton never thought his life would change.
At fifteen, he was stuck in the Middle Class for life. His biggest problem was getting his father to accept the fact that he didn't want to take over the family farm, but wanted to be a teacher.
But then the Collectors came to town.
They're looking for a Mind-Power - one of the strongest they've ever seen. It could be Clayton's brother Trey, or it could be his sister Macy.
Or it could be Clayton himself.
