From New York Times bestselling author Lauren DeStefano comes an atmospheric and spine-tingling story about four children who dream in tandem.
Tucked deep in the woods and surrounded by a great iron fence lies Brassmere Academy for the Extraordinary, a school for orphans with strange and wonderful gifts. Twelve-year-old Plum has lived there for as long as she can remember. Each night, she ventures into her dreams alongside her three best friends, Vien, Gwendle, and Artem to fight monsters and journey on dangerous quests.
But one night, Plum gets a mysterious warning that she and her friends are no longer safe. And the next morning, Artem is nowhere to be found.
As Plum, Vien, and Gwendle search for their friend--in both the dreaming and waking worlds--they start to uncover alarming secrets about Brassmere and its intentions. Will they be able to find Artem before it´s too late, or will they be next to disappear?
