Welcome to Fossbridge, where the only thing worse than being seen is disappearing in the crowd.

The Fossbridge School for Timid Girls exists outside of time and place. Here, girls frozen in their sixteenth year live for their moment of triumph and freedom: Graduation. Divided into tiers and kept on a strict schedule, memories of the outside world fade quickly as the rigid rules and complex social hierarchy that dominate the girls’ days take over. Success means winning not only the approval of their teachers but their rivals as well. Top girls Graduate to resume their forgotten lives, while others watch and wait for any opportunity to climb. And then there are Leavers—but we don’t really talk about them…

When two new arrivals dare to challenge Fossbridge’s delicate ecosystem, cracks begin to show in the school’s serene facade. Girls hear voices in their rooms at night, civilized debates turn to vicious brawls, and sabotage lurks in every corner—their crumbling sanctuary’s darkest secret is about to be unleashed. After all, the one eternal truth about Fossbridge is that timid girls can change.
