Where the Water Runs Wrong: A Debt of Moytura Novel. The Debt of Moytura, #3

The limestone splits open under Orla Kincaid's hands. She came to the plain of Moytura for a routine survey. What she finds instead is a crack in the old ground - and inside it, a brass ball marked with an ancient eye. When blood touches the stone, something buried beneath the field wakes for the first time in three thousand years. The water begins to run the wrong way. The ground knocks from below.
The voice of Orla's dead lover comes through the dark. And Nessa Byrne, wounded on the plain, begins to hear the road beneath the world. A match interrupted three thousand years ago left a debt unpaid. Now the field has chosen new players: Orla, Nessa, Finn, and Ciaran - and the bound road runs through water, stone, memory, and blood. Moytura does not forgive mistakes. And some debts do not stay buried.
