Just when Eleanor thinks she's free, something crawls from Ashford's grave. But it's not him-it's something worse. The entity has abandoned its human hosts and now walks freely, shapeshifting into something more powerful than ever before. It is no longer bound to Blackwood. It is bound to Eleanor. No matter where she runs, it follows. With the help of Kane and ex-priest Caleb, Eleanor sets a trap in the desert, performing a dangerous ritual known as the Ritual of Oblivion, which will erase the entity from existence. But there's a price-if the entity is erased, Eleanor might be erased too.
