Thornhill by Pam Smy is a hybrid graphic novel in the style of The Invention of Hugo Cabret with the present day story of a lonely girl living next door to the ruins of an old mansion, and the 1982 story of the last girls to live in that mansion when it was a school for wayward girls.
The story unfolds in a series of moments with the present day girl in her upstairs room over looking the burned out, overgrown remains of the building, and later with her explorations of the grounds next door. These scenes are cut together with diary entries from a girl who lived next door and was horrifically bullied by the other girls.
It's the counter play between the dark lines of the architecture with the darkness of Mary's story where the parallels between past and present emerge. The ending, while tragic, isn't a surprise. It's a satisfying pause in what will probably be a series of events linking the two buildings together.
