Deadly!

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.
