When Chester discovers he can mind jump, his sister Amy wastes no time in putting his new skills to work boosting the viewing figures on her video blog. And when a TV company takes them global, he does his most daring mind jump yet, into the brain of Tito the gorilla. The trouble is, when he tries to return to his own body - it's gone!

Has it been stolen? But who would want it, and why? And how come Chester suddenly has the urge to search Amy's hair for fleas? The quest to find the answers takes him on a journey beyond his wildest imagination.

A fast-paced, mind-boggling and hilarious yet thought-provoking read from the author of The Imagination Box series.
