The Stolen Heir Duology Boxset

Eight years have passed since the Battle of the Serpent. But in the icy north, Lady Nore of the Court of Teeth has reclaimed the Ice Needle Citadel. There she is using an ancient relic to create monsters of stick and snow who will do her bidding and exact her revenge. Suren, child queen of the Court of Teeth, and the one person with power over her mother, fled to the human world, where she lives feral in the woods. Lonely, and still haunted by the merciless torments she endured in the Court of Teeth, she bides her time by releasing mortals from foolish bargains.
