Parallel stories set in different times, one told in prose and one in pictures, converge as a girl unravels the mystery of the abandoned Thornhill Institute next door.

1982: Mary is a lonely orphan at the Thornhill Institute For Children at the very moment that it's shutting its doors. When her few friends are all adopted or re-homed and she's left to face a volatile bully alone, her revenge will have a lasting effect on the bully, on Mary, and on Thornhill itself.

2017: Ella has just moved to a new town where she knows no one. From her room on the top floor of her new home, she has a perfect view of the dilapidated, abandoned Thornhill Institute across the way, where she glimpses a girl in the window. Determined to befriend the girl and solidify the link between them, Ella resolves to unravel Thornhill's shadowy past.

Told in alternating, interwoven plotlines--Mary's through intimate diary entries and Ella's in bold, striking art--Pam Smy's Thornhill is a haunting exploration of human connection, filled with suspense.
