Balanced on the Blade's Edge - Lindsay Buroker

Balanced on the Blade's Edge is the first novel in the Dragon Blood series.

Colonel Ridge Zirkander has never had great impulse control. As the most famous flyer in the Iskandian army, it hasn't always been a problem. Punching out a foreign diplomat is the exception to that rule. Ridge is now commanding the prison in the Ice Blades Mountains. That a sorceress, who has been buried beneath the prison for 300 years, wakes up when Ridge gets there is just a coincidence. Or is it. Very highly recommended.
