Soulblade - Lindsay Buroker

Soulblade is book seven in the Dragon Blood series.

Ridge crashed into the mountains after defeating the dragon Morishtomaric. Almost everyone accepts that he's dead. Not Sardelle. While she's on a quest to find Ridge dead or alive the rest of the squadron is on a secret mission to kidnap the Cofah emperor. It all comes together in a dragon fighting, castle destroying melee. Very highly recommended.
