Leo Lennox has made a mistake. A massive, world-altering mistake. Now, the secret his shape-shifter ancestors have kept hidden for thousands of years is in danger of being discovered - all because he insisted on going to school camp.

It's no place for a thirteen-year-old Turner still struggling to control his ability to transform into animals. Surrounded every minute of every day by his classmates - including his secret crush, and a pair of terrifying bullies - Leo is going to find out just how much he still has to learn.

But when he discovers a fiendish plot, Leo realises that surviving camp is going to be the least of his worries.
