Dinosaurs and portals, and a girl who can find both in the latest book in the Hugo and Nebula Award-Winning series.

Antsy is the latest student to pass through the doors at Eleanor West's School for Wayward Children.

When her fellow students realize that Antsy's talent for finding absolutely anything may extend to doors, she's forced to flee in the company of a small group of friends, looking for a way back to the Shop Where the Lost Things Go to be sure that Vineta and Hudson are keeping their promise.

Along the way, temptations are dangled, decisions are reinforced, and a departure to a world populated by dinosaurs brings untold dangers and one or two other surprises!

A story that reminds us that finding what you want doesn't always mean finding what you need.
