Ireland 188 A.D: A land of tribal affiliations, secret alliances and treacherous rivalries.

Liath Luachra, the young - and deadly - woman warrior, has survived two brutal years with mercenary war party "The Friendly Ones" but now the winds are shifting. Dispatched on a murderous errand where nothing is as it seems, she must survive a group of treacherous comrades, the unwanted advances of her battle leader and a personal history that might be her own undoing.

Clanless and friendless, she can count on nothing but her wits, her fighting skills and her natural ferocity to see her through.

Woman warrior, survivor, killer and future guardian to Irish hero Fionn mac Cumhaill - this is her story.
