Eight centuries ago the first Knight of the Word was commissioned to combat the demonic evil of the Void. Now that daunting legacy has passed to John Ross—along with powerful magic and the knowledge that his actions are all that stand between a living hell and humanity’s future.

His only hope is Nest Freemark, a college student who wields an extraordinary magic all her own. Five years earlier, Ross had aided Nest when the future of humanity rested upon her choice between Word and Void. Now Nest must return the favor. She must restore Ross’s faith, or his life—and hers—will be forfeit…
