How to Live Forever — Colin Thompson

A charming tale of the perils of immortality, from one of Australia's best storytellers. Peter lives with his mother and grandfather in the museum, which has the most weird and wonderful exhibits and a hundred secret doors. When his grandfather gets sick, Peter decides to search for his long-lost father. Instead, he finds a strange old woman who gives him a book called How To Live Forever but makes him promise never to read it. Trapped in a world where books are houses, Peter meets a girl called Festival, and together they look for the Ancient Child, who has the answers to everything.
