When Amy arrives home for her birthday tea, her parents have vanished and in their place is a baby she's never seen before. At around the same time Sprocket wakes up naked on a deserted mountainside and realises that he has lost his memory. Both kids set out on journeys to find the people they belong to, little knowing that they will soon join forces and embark, with the baby, on the deadliest quest of their lives. Morris Gleitzman writes Amy's story and Paul Jennings Sprocket's, with each of them contributing alternate chapters.

'this book is fantastic when little people later turn out to be grown-ups! there is a lot of carin in this book sprocket helps amy that was the cute part. late on when amy thought she was cariing her sister she was not it was her mum! at the end amy dad reunites them and amy and sprockkets ends up loving each other so adorable!'

‘This book is a mixture of stories all in one, Amy’s story, Sprocket’s story, and the Brat’s story. But this was done in an easy reading way and didn’t confuse me at all. Most of the time the book is very funny but it also is sometimes quite sad. It had the strangest story line, stranger than any other book I’ve read! I found this book very exciting and enjoyed everything about it!’
