Finding the Lost — Mark Cheverton

Billy and Ali hate their lives in the underground refuge of Haven. Being smaller and weaker than the other kids, they are constantly the targets of teasing and abuse, bullied from all sides, making them doubt their own value. But then they are given a chance to make a difference, use their psychic powers to help the unfortunate and save the damned from a fate worse than death. Sneaking back into Azule City with the chief of the Gifted, Farzin Arash, Billy and Ali use their psychic powers to penetrate a secure facility, narrowly avoiding heavily armed security forces, and try to save hundreds of hopeless souls, lost and forgotten. Billy and Ali doubt their own strength but try to do that which has never been done before, unaware of the danger that exists, their very sanity hanging in the balance. Will they survive? Will they find those that are lost, or will they themselves become lost.
