Of Blood and Fire (The Bound and the Broken, #2.5) by Ryan Cahill

Born in fire. Tempered in blood.

Epheria is a land divided by war and mistrust. The High Lords of the south squabble and fight, only kept in check by the Dragonguard, traitors of a time long past, who serve the empire of the North.

In the remote villages of southern Epheria, still reeling from the tragic loss of his brother, Calen Bryer prepares for The Proving—a test of courage and skill that not all survive.

But when three strangers arrive in the village of Milltown, with a secret they are willing to die for, Calen’s world is ripped from under him and he is thrust headfirst into a war that has been raging for centuries.

There is no prophecy. His coming was not foretold.

He bleeds like any man, and bleed he will.
