The Man with the Crystal Ankh (Hollow Oak) (Volume 1)

Everyone’s heard the legend of the hollow oak—the four-hundred year curse of Sarah Willoughby and Preston Grymes. Few realize how true it is. Sarah Durante awakens to find herself haunted by the spirit of her high school’s late custodian. After the death of his granddaughter, Custodian Carlton Gray is not at peace. He suspects a sanguisuga is involved—an ancient force that prolongs its own life by consuming the spirits of others. Now, the sanguisuga needs another life to feed its rotten existence, and Carlton wants to spare others from the suffering his granddaughter endured. That’s where Sarah comes in. Carlton helps her understand that she comes from a lineage of ancestors with the ability to communicate with the dead. As Sarah hones her skill through music, she discovers that the bloodlines of Hollow Oak run deep. The sanguisuga is someone close, and only she has the power to stop it.
