Oath of Iron and Bone. Oath of Iron and Bone, #1

Some debts are paid in gold. His will be paid in blood.???????In a world of shadowy gambling dens and quiet alleys where fate is a pulled silver thread, easily snapped. Here, every wager is a risk, every loss brings you closer to the knife's edge, and every debt is an oath that will be honored-one way or another. For a tired soldier running from his ghosts, the final bill is coming due. Corius is a veteran of forgotten wars, haunted by the voices of battle that only cheap drink and the turn of a card can quiet.
A skilled warrior by trade, he has become a gambler by vice, chasing losses with a desperation that has left him broke, hungry, and deeply in debt to the city's most unforgiving men. His skill with a blade is undeniable, but his luck has finally run dry, leaving him exposed and cornered. The predators who own his debts are circling, but a far greater danger has just stepped out of the shadows.
