This trilogy follows the story of John Chen and Emma Donohoe. They have just found out that Emma has Demon blood and they have suffered the miscarriage of their first child. The Sidhe—or Shining folk, who defeated the Western Shen a thousand years ago—are prepared to do battle against the Western Shen to retain their dominance. Emma’s allegiance is torn: to fight for her kind, the Western demons she is descended from, or to stand alongside her beloved Xuan Wu.
