The heroine of Druid Warrior’s Heart (Celtic Stewards Chronicles, book 2), Ruth Macken, is part of a long line of female stewards, owner of an Irish farm deemed a sacred battleground by the gods of the Tuatha dé Danann. However, she lives in a Medieval world, where most men don’t believe in the gods anymore, so she must keep her blessing silent, even when the Tuatha dé Danann’s immortal druids and warriors come to her requesting use of the sacred ground. For his part Balor sends enemies against her, and though Ruth has a Tuatha dé Danann warrior who defends her, she fights too and sometimes, alone. For instance, when Balor sends evil dreams in which she faces him down, alone…a showdown her warrior can’t even know about, let alone participate in.
Passion’s Sacred Dance (Celtic Stewards Chronicles, book 1)
In Passion’s Sacred Dance, our heroine, Stacy, runs a history museum that also sits on ground sacred to the Tuatha dé Danann. When they (and their enemy Balor) each come to her requesting permission to use said ground, it’s up to her to decide which side to give it to. In the course of the book, though she does fall in love with a Tuatha dé Danann warrior, she faces the evil Balor’s men down quite a few times, sometimes, singlehandedly.
