Grimm series (Adam Gidwitz)

Follows Hansel and Gretel as they walk out of their own story and into eight more tales, encountering such wicked creatures as witches, along with kindly strangers and other helpful folk. Based in part on the Grimms' fairy tales Faithful Johannes, Hansel and Gretel, The seven ravens, Brother and sister, The robber bridegroom, and The devil and his three golden hairs.

A brother and sister must venture through kingdoms and forests haunted by demons and ogres, all the while seeking their way home. And they must face the most frightening monster of all: death. Enter, if you dare, a world filled with cruel stepsisters, ghastly suppers and a terrifying little man called Rumpelstiltskin.
