Dana’s best friend Kitty has died in a car accident, and the only ray of light in the misery is when her grandmother appears in her spiffy red sports car to cheer her up. At the same time a nightmarish shadow appears to hunt Dana and she has to flee from her ordinary life with grandma, who turns out to be something quite different than what Dana had thought - a Huntress of Shadows. The truth about her ancestry is not an easy thing for Dana to accept - she was deliberately created to perform a task, to find something that should stay hidden, or it might threaten the world of humans as Dana knows it. Her existence is tied to the myth of the Nephilim, the descendants of angels, and her creator was someone who commands the forces of chaos and darkness, the source of all horror myths of humankind. Dana learns there is a world of shadows, the afterlife, dreams and time travel, surrounding the physical world, hidden behind a thin veil - and that there are ways to enter it from the physical world. Dana has no option - she is being hunted by creatures of darkness, and the hunt can only end in either Dana and everyone she loves being captured and turned into creatures of darkness - or Dana finding what she was created to find. Her hunters have skills no ordinary human can escape - but Dana is not an ordinary human. Nor is Daniel, the leader of a hidden Center fighting the darkness. Together with a chosen team they could travel the Unseen Worlds that surround the physical world, into the past, following a clue written down in ancient Egypt, and then walk the Trail of Angels, and find the hidden mystery before the dark creatures do. Dana must prepare for a long search in another time and place, knowing that both she and Daniel are wanted and hunted by the darkness. At stake is her love, and the destiny of the human kind.
