About This Book
In a story that spans two thousand years, Aoibh Wood pulls readers between ancient Ireland and present-day Boston, weaving a mystery that begins on the eve of a legendary mythological battle and ripples forward into the modern world. When Cait Reagan's sister crosses the Atlantic expecting a funeral, she finds something far more complicated—and what she uncovers threatens to reshape everything the Reagan family thought they knew about Cait, about themselves, and about the hidden forces that have been moving the pieces all along. The emotional stakes here run deep, rooted in sisterhood, grief, and the particular ache of secrets kept across centuries.
What sets this third installment apart is Wood's confident command of dual timelines, slipping between ancient divine intrigue and gritty contemporary urban fantasy without losing momentum in either. The Irish mythology feels lived-in rather than decorative, and the Boston Preternatural Investigations Unit continues to grow more textured and specific with each book. At 454 pages, the novel earns its length, layering character revelation and world-building in ways that reward readers who have followed the series while delivering enough grounding to keep the mythology from overwhelming the story's human—and very inhuman—heart.
