This little book is number 2 in the series called Deadly but could be read without the others. I believe all of the six stories are available in one volume now. 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 We also have books 1, 4,5, and 6 in the Little Library of Rescued Books.
