It’s midnight on Christmas Eve, and agoraphobic Emma Addison has inadvertently summoned the devil. Frantic to appease her unbidden guest, she surrenders a cherished stone carving of Kuan Yin. But this is a terrible mistake, for it opens a door she cannot close.

In exchange for her unwitting concession, Emma is awarded a mysterious power, an unwelcome gift the devil refuses to take back. And now she faces some disquieting choices. Because if the devil is real, doesn’t that mean God is too? But if God is real, then why is the world such a mess and so desperately wanting the very power in her hands?

Hazarding a narrow path between darkness and light, Emma embarks on a maverick quest to extinguish earthly suffering, an odyssey that will shatter her every notion of truth. Follow her journey to the furthest reaches of faith and doubt, and discover a realm beyond both—an imperishable domain invulnerable to demon and angel alike.
