Dead Reckoning — Gail Z. Martin

An old enemy bent on revenge exacts a terrifying price, forcing Jonmarc and his soldiers to choose between conscience and survival. Pushed to the breaking point, Jonmarc must protect the soldiers he commands while an old curse plays out its vengeance and a traitor maneuvers to gain a crown.

Soldier. Fight slave. Smuggler. Warrior. Brigand lord. If you've met Jonmarc Vahanian in the Chronicles of the Necromancer and Fallen Kings Cycle books, you don't really know him until you take his journey.
