"Thirteen-year-old Will Tuttle lives a boring, friendless life trapped in a sterile bubble, suffering from mysterious allergies no doctor can explain. But everything's about to change as he learns his countless allergies have a single, bizarre source--enchants, a society of half-humans that have lived among mankind for generations. Their existence is history's best-kept secret. Spotting them is next to impossible. Enchants have become far too clever at keeping their tails, scales, claws and feathers hidden from everyone . . . everyone except Will." -- p. [4] of book jacket.
