A vampire mentors three sibling Witches as they struggle to balance life, with duty, as protectors of The Demon Isle…Off the coast of New England is the Demon Isle, a place notorious for its weird stories, ghostly encounters and mythical creatures. The sheriff of The Demon Isle needs help solving a murder. Michael Howard, a death reader, along with Charlie Howard (a little more than human) set off to help the sheriff solve this case when they meet a damsel in distress that turns out to be more than she appears.
Meanwhile, their sister, Melinda, gifted with prophetic dreams, races against the clock to save a friend, currently haunted by a malevolent spirit in search of a body to possess. But when the moment comes, the siblings suddenly have an unexpected choice to make: allow the possession, or banish the spirit, before it can pass on a message, which the spirit claims is from a deceased Howard witch.
