Plot summary

Louise cannot die. She is one of a line of women descended from Lilith, the mother of demons, and the women of that line feed on a man's soul at every full moon; a woman who does not feed bleeds to death, and that is why every man Louise sleeps with dies. Charlie was her first love, in the 1920s, and she killed him by accident before she came to understand what she was. A hundred years later, Charlie returns to her, reincarnated, and Louise struggles to keep away from the man she loves, knowing she risks losing him once more.
