The twenty-ninth mystery in Peter Tremayne's long-standing and much-loved series, featuring 7th-century Irish super-sleuth Sister Fidelma

Sister Fidelma returns in Bloodmoon, the twenty-ninth Celtic mystery by Peter Tremayne, acclaimed author of Penance of the Damned and Night of the Lightbringer. If you love Ellis Peters, you'll be gripped by Bloodmoon and the Sister Fidelma series.

Ireland. AD 671. Sister Fidelma has a mission, and she is sworn by oath to reveal her purpose to no other. The secret investigation leads Fidelma and her companions to the abbey of Finnbarr to question the abbot. But before they have a chance to speak to him, the abbot is found murdered - and the young girl suspected of the crime has fled the scene.

Despite their protests, Fidelma's cohorts agree to accompany her in pursuit of the girl for answers. But as vicious rumours spread, accusing Fidelma's family, the Eoghanacht Kings of Cashel, of conspiring to assassinate the High King and abduct his wife, Sister Fidelma's life is placed in mortal danger.

Unable to tell the truth of her quest to anyone, including her husband Eadulf, Fidelma's time is running out - and now she has no choice but to face the challenge, and her enemies, alone.
