Wild-born by Adrian Howell

A young teen is torn from his up-to-then peaceful life when he develops powerful telekinetic abilities. His parents murdered, his sister kidnapped, the boy must mature quickly to survive in a sinister world of warring paranormal factions, deadly religious cults and terrifying government organizations. Following several weeks on the run, he finds refuge in the company of a psychic family, where he befriends a young telepathic child with a dark and painful past. All too soon, however, his new family is attacked, leaving both children locked in an underground prison from which there is seemingly no escape.
