Raptor - Lindsay Buroker

Raptor is the sixth novel in the Dragon Blood series.

Ex-Lieutenant Caslin Ahn is wracked with guilt over the death of Apex. Ahn had no plans to get back in a flyer, but when the king asks it's hard to say no. She is going to wield the magic killing sword Kasandral in hopes of slaying the golden dragon that's terrorizing the kingdom. Can Ahn kill the dragon and keep Kasandral from attacking more of her teammates? Very highly recommended.
