Demon's Quest (High Demon #4)

After Reah's brush with death, she is understandably distrustful of most of her mates. Striking out on her own, she is determined to investigate a rash of child disappearances across the universes, in and outside the Alliances. The evil she discovers in the course of her investigations could bring all worlds to their knees if Reah doesn't find a way to destroy it.
