The Trinity. The Trinity Saga, #1

Three legendary mercenaries. Three buried vendettas. One contract that will shatter them all. They are called the Trinity, and there is no deadlier blade for hire in all the known world. Kage - the smiling swordsman, the finest blade alive, whose easy charm hides a grief he will show no one and a past chained to the very empire he's been hired to walk into. Ishtar - the spear-dancer from the far south, as brilliant as she is beautiful, loyal to a cause not one of her companions suspects.
Tren - the silent giant in the steel wolf-helm. Eight feet of muscle and dark steel, mute for ten years, hunting a single monster across the ruins of his stolen home. When a grieving king hires them to rescue his daughter from the demon-haunted empire of the south, it has every look of just another job. But Emperor Melok's empire runs on a fuel far darker than gold - the souls of the conquered, harvested and fed to a thing that clawed its way up out of hell - and every member of the Trinity is carrying a secret reason of their own for passing through its gates.
Each of them has a score to settle inside that black fortress. Each of them means to settle it. And the terrible truth none of them will say aloud is this: if all three get what they came for, the Trinity will not survive it. Because in a world where everyone wears a mask, the most dangerous thing of all is to finally take yours off. The Trinity is the first book in a planned epic dark-fantasy trilogy - a story of vengeance, brotherhood, and buried truths, for readers of Andrzej Sapkowski's* The Witcher*, and Kentaro Miura's* Berserk*.
