Echo's carefully structured world falls apart after her father leaves for the city and mysteriously disappears. Believing he is lost forever, Echo is shocked to find him half-frozen in the winter forest six months later, guarded by a strange talking wolf - the same creature who attacked her as a child. The wolf presents Echo with an offer: for her to come and live with him for a year. But there is more to the wolf than Echo realises, including a history she can't remember.

In his enchanted house, Echo discovers centuries-old secrets, a magical library filled with books-turned-mirrors, and a man named Hal who is trapped inside of them. As the year ticks by, Echo must solve the mystery of the wolf's enchantment before it's too late - otherwise Echo, the wolf, and Hal will be lost forever.
