Watershed Series by Douglas Niles

Book One of the Watershed Trilogy. For centuries, the pristine lands of the Watershed were at peace. But now only a handful of heroes remains to fight against a dark god who has one all-consuming thirst-the destruction of the Watershed.

In the sequel to Breach in the Watershed, the man of Three Waters and his companions struggle to unite the humans and the Faerines in order to stem the tide of evil Darkblood that threatens to destroy all that is good in the world.

"The Watershed Trilogy" comes to an end. As the human and Faery alliance make their final stand against the Dark Lord's armies, the Man and Woman of Three Waters set out to fulfill their destiny beyond the Watershed where only they can vanquish the heart of evil.
