Sophie Malone never expected to find Celtic treasure or to end up in a fight for her life in a dark, desolate cave while on a trip to a remote Irish island. Now she has questions to answer.

Joined by detective Cyrus "Scoop" Wisdom, she faces the greatest challenge of her life: someone is using ancient rituals to commit modern-day murder-and the killing has only just begun.
