Teens, especially those not in the über-popular set, know all about feeling invisible. But what would happen if you actually did wake up invisible one day? Fifteen-year-old Bobby is faced with this curious predicament in Andrew Clements's compelling novel Things Not Seen. Doing his best to adapt, Bobby informs his parents and grows more and more frustrated as they try to control his (unseen) life. Attempting to take matters in his own hands, he ventures out--naked--to the library, where he meets a blind girl who becomes a natural confidant. The ensuing drama, involving a nationwide search for other invisible people and a break-in to the computer database at Sears, Roebuck legal department headquarters ("News flash: Invisible people make excellent spies and thieves") is authentic enough in detail to allow readers to overlook the nuttiness of it all. Teens will identify with Bobby's experience of being essentially invisible. Highly recommended. (Ages 11 to 15) --Emilie Coulter
