"Haddix will be well known to many younger listeners as the author of the immensely popular Shadow Children series. Her latest addition to the science-fiction genre is reminiscent of the work of Madeline L'Engle. Chris Sorensen's youthful portrayal of 13-year-old Jonas and his friends is perfectly believable. Jonas has always known he was adopted. But when he and his friend Chip start getting strange letters, they discover they may be part of a cover-up involving a plane that appeared out of nowhere one day, full of babies. Overall, Sorensen delivers a solid performance, though his pace might have picked up a bit in places to increase the story's tension. Fans of the author will not be disappointed. D.G.
