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—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, otherwise Echo, the wolf, and Hal will be lost forever.

In the dark, cold reaches of the north lives a storyteller and his daughter. He told his daughter, Satu, many stories—romances like the girl who loved a star and changed herself into a nightingale so she could always see him shining—but the most important story he told her was his own. This storyteller was once the formidable North Wind, but he lost his power by trading it away in exchange for mortality—he loved her mother too much to live without her. The loss of his magic impacted more than just their family, however, and now the world is unraveling in the wake of this imbalance. To save the North, Satu embarks on a perilous journey to reclaim her father's magic, but she isn't the only one searching for it. In the snow-laden mountains, she finds herself in a deadly race with the Winter Lord who wants the North Wind's destructive powers for himself. Satu has the chance to be the heroine of her own fairy tale, only this one has an ending she never could have imagined. A hauntingly beautiful fairy tale about love and loss, this Echo North companion novel is perfect for fans of the Winternight Trilogy.
