In 1982 at an orphanage named Thornhill (Roaring Brook, $19.99), Mary fills the pages of her diary with shocking accounts of her suffering at the hands of another girl who lives downstairs. Mary only feels safe in her attic bedroom, where she spends her time reading and making puppet companions. Decades later, Ella has just moved to a new home that overlooks the abandoned orphanage. No one has lived there since an orphan girl was murdered years ago—so why does Ella keep seeing a figure in the lit attic window and finding puppets in the garden? Author/illustrator Pam Smy cleverly tells Mary and Ella’s stories in alternating journal entries and plot-propelling illustrations until the girls’ worlds finally collide in an unexpected and spine-tingling twist. Ages 10-13.
