In post-World War I England, eleven-year-old Triss nearly drowns in a millpond known as "The Grimmer" and emerges with memory gaps, aware that something is terribly wrong, and to try to set things right, she must meet a twisted architect who has designs on her family.

"When Triss wakes up after an accident, she knows something is very wrong. She is insatiably hungry, her sister seems scared of her, and her parents whisper behind closed doors. She looks through her diary to try to remember, but the pages have been ripped out. Soon Triss discovers that what happened to her is more strange and terrible than she could ever have imagined, and that she is quite literally not herself. In a quest to find the truth she must travel into the terrifying underbelly of the city to meet a twisted architect who has dark designs on her family before it s too late . . . Set in England after World War I, this is a brilliantly creepy but ultimately loving story of the relationship between two sisters who have to band together against a world where nothing is as it seems."--From publisher.
