Synopsis: Publisher: All Isla Macallen wanted was a simple existence on her little Scottish island, free from her mother's insanity and the prying eyes of neighbors. What she got was embroiled in a war for the souls of mankind. A war of good versus evil, of witches versus demons, and Isla learns that she alone can end it. Dr. Jeremiah Rousseau was a self-proclaimed nomad, traveling the world researching paranormal phenomena. He doesn't expect his research to lead him to Scotland, and to the woman who will turn his world upside down. Together with a facetious shapeshifting animal spirit guide, Jeremiah and Isla discover that she is part of an ancient bloodline bred to protect the gateways between the human world and the spirit world, to keep evil demons from destroying them. They must find the key to defeating Alastore, the demon king, and closing the gate before Samhain, when the veil between the worlds is lifted. Alastore does everything in his power to eliminate them but, unbeknownst to all of them, Isla is the only one with the ability to stop him for good.
