The Ferryman — Wendy Saunders

Olivia has been left reeling from one shock after another. Betrayed by her family and still trying to piece together the broken fragments of her life. She and Theo must also try to figure out how to stop Nathaniel, the demon from seventeenth century Salem, who has been let loose on the quiet unsuspecting town of Mercy. As if that's not enough the town is suddenly overwhelmed by the spirits of the dead. Not just one or two but hundreds. When the vengeful spirit of a wronged man and the soul of a murdered girl spread chaos through the town, Olivia and Theo must find a way to force all the spirits back to the other side and close the door to the otherworld. The problem is the door was opened on purpose and if Olivia and Theo can't figure out how and why it might just remain open permanently.
