Book excerpt: When her distant aunt and uncle die, Amelia Howling and her parents move in with Amelia's orphaned cousins. Luckily, the house is large, filled with nooks and crannies perfect for hiding. The house was built years ago by a creature named Horatio, who has the power to travel through time and memories. He's been waiting for the perfect human inhabitant, and lures Amelia into his world. Her cousins were full of good memories-- until Amelia noticed that once she and Horatio visited a memory, it was gone forever. Can she help them recover their minds, and break the perfect clockwork of the evil Calendar House?
