Mary Jane, Maude, and Jack are playing in the attic of their rickety old house when Maude makes an unexpected discovery: a mirror that leads into another world. At first the children are delighted to play with their new animal friends in Devorian, but the situation becomes dangerous when an evil witch frozen in time kidnaps Mary Jane and tries to use her to take over Devorian. Maude and Jack set off to save their sister and Devorian at the same time. With the help of the magical beasts of Devorian--a small but noble group of the most powerful mythical creatures in the land--the three children race against time to find the Horn of Duhaim, the only thing that stands between the witch and her goal of conquering all of Devorian. Inspired by classical children's literature such as The Lion, Witch and the Wardrobe series, The Mirror in the Attic explores themes such as good and evil using vocabulary intended to educate and challenge young readers.
