A Feral Darkness(2001)

Doranna Durgin

As a child, dog-loving Brenna Fallon naïvely invokes an ancient Celtic deity to save her beloved hound--and inadvertently anchors the new-found power at a spring on her family's farm.

She doesn't know she's also left an opening for a far more malevolent force.

Years later, thanks to the actions of several angry young men, Brenna discovers the terrible potential of that gateway. With a devastating plague unfolding abruptly around her, she must depend on her wits, a stranger she doesn't trust, and a mysterious stray dog who becomes more than just a faithful companion as she struggles to drive back the threat of a modern Black Death.

Welded by a desperate sacrifice, woman, man, and dog face the feral darkness together.
