While hedge-witch Mama Grace tends to the needs of the poorer denizens of Bellamdale, respect for her power does not extend to her foster daughter, Sally Founder. Trying to save a cat from local bullies, Sally finds herself in dire straits, until rescued by the Nephilim Samdriel. In exchange, the young girl becomes the host for his disembodied spirit.
Their merging grants Sally some of Samdriel's power, as long as their relationship remains secret—even as other spirits grow restless and call for blood. When evil omens spur new violence, Sally is granted sanctuary by Lady Bellingham of Briarstone Manor with promises of protection and an education. Yet, the young girl's new home holds secrets of its own, and pretty gowns and fancy balls cannot keep the growing darkness at bay. Sally unwittingly becomes part of a broader game that has been played for untold centuries. Could even Samdriel's power be enough to save the witch's foundling and those she loves as an ancient evil comes searching for a prize that threatens the world?
