James Foley

Return to James Foley’s hilarious series about Sally Tinker, the world’s foremost inventor under the age of twelve.
Sally Tinker is facing an extraordinary new adventure. The brain-enhancing nanobots she is testing have been accidentally swallowed by her baby brother, Joe.
The only way to stop Joe from turning into a superbaby and wreaking super havoc is to shrink herself and travel inside Joe’s body on a journey to tackle the problem head-on. What could possibly go wrong? As it turns out, this is only the beginning …

‘Gastronauts is one of the best books I have ever read … One of the best things about this book is definitely the illustrations because they are detailed and realistic.’
