Where it all began―the first three books in Seanan McGuire's multi-Hugo and Nebula Award-winning Wayward Children series. Join the students of Eleanor West, and jump through doors into worlds both dangerous and extraordinary.

Book 1: Every Heart a Doorway

Book 2: Down Among the Sticks and Bones

Book 3: Beneath the Sugar Sky

Children have always disappeared under the right conditions; slipping through the shadows under a bed or at the back of a wardrobe, tumbling down rabbit holes and into old wells, and emerging somewhere... else. But magical lands have little need for used-up miracle children. Meet Nancy, cast out of her world by the Lord of the Dead;

Jack and Jill, each adopted by a monster of the Moors; Sumi and her impossible daughter, Rini. Three worlds, three adventures, three sets of lives destined to intersect.
