Echo North

Echo Alkaev's safe and carefully structured world falls apart when 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 amp;mdash; the same creature who attacked her as a child. The wolf presents Echo with an ultimatum: if she lives with him for one year, he will ensure her father makes it home safely. But there is more to the wolf than Echo realizes.

In his enchanted house beneath a mountain, each room must be sewn together to keep the home from unraveling, and something new and dark and strange lies behind every door. When centuries-old secrets unfold, Echo discovers a magical library full of books-turned-mirrors, and a young man named Hal who is trapped inside of them. As the year ticks by, the rooms begin to disappear and Echo must solve the mystery of the wolf's enchantment before her time is up amp;mdash; otherwise Echo, the wolf, and Hal will be lost forever.
