Written by Tim Wynne-Jones, this is the story of 16-year-old Declan Steeple who has great grades, a loyal best friend, an adoring little sister, a stepmother who keeps her distance and an independently wealthy father. If it seems a little too perfect, that's because it probably is. He begins to unravel the mystery of his mother's leaving him when he was 10 and why his father turned the family mansion into a kind of museum, the House of Memory, after Declan hitches a ride home from school one fateful day.
