Soulkeeper (The Keepers #1)

In the first book of USA Today bestseller David Dalglish's epic fantasy trilogy a warrior priest must answer the call and protect his world from monsters that were once only legend when ancient magic suddenly returns to his land.
Devin Eveson is a Soulkeeper, traveling through remote villages as a preacher and healer. But when a dragon awakens--the size of a mountain and leaving great chasms in its wake--the veil is torn, flooding the land with ancient magic and forgotten races. Now Devin must set aside his words of peace and accept his new role: slayer of monsters and protector of the human race.

But not all the creatures that have re-awakened mean humanity harm. And as Devin slowly befriends people of these new races, his discomfort in his role grows. But Soulkeepers must slay without mercy. And even sympathizers risk their wrath.
