First Frost has touched Cape Fen, and that means Baron Dire has returned. For as long as anyone can remember, the baron has haunted the town come winter, striking magical bargains and demanding unjust payment in return. The Serling sisters know better than to bargain lest they find themselves hunted by the baron’s companion, the Wolf. But then the Wolf attacks Eliza’s sister, Winnie. They escape but know the Wolf will be back to collect its dues. Winnie would never bargain, so that must mean someone else has struck a deal—with Winnie as the price. Eliza embarks on a journey to save her sister. If she can learn the truth, she might be able to protect Winnie, but the truth behind the bargain could put her own life in danger. This beautiful and magical debut is about sisterhood, sacrifice, and what happens when the dreams we hide within ourselves come to light.
