Jane Doe is in more danger than ever before. Her father is still imprisoned. The Manor, the hallowed world between worlds, is still dying. The villainous Roth is still searching for the mythical, all-powerful Cradle Sea. Worst of all, Jane has learned that she is, literally, one of the keys needed to stop him. Problem is, she's stranded in the dying world of Arakaan, Roth's home, and its people have some surprising secrets of their own.

With a little help from her pyromaniac pal Violet and her doubtful ally Hickory, Jane must find the courage to accept her destiny and face her darkest fears, while every soul in every world hangs in the balance.
