POWERHOUSE (4) by Rebecca York: Shelly Young walked away from Matt Whitlock five years ago when it was apparent he didn't want a permanent relationship. She chose to keep their son a secret, but when the boy is kidnapped she has nowhere else to turn. After the initial shock, Matt starts to wonder if his son's abduction has anything to do with his own kidnapping, his special powers and the evil Blue of his nightmares. At the same time Shelly wonders if Matt is a danger to himself, or the only salvation her son might have. York delivers a great mystery with strong characters and a well-developed plot.
