The Dragon Eater - J. Scott Coatsworth - Bog

Raven's a thief who just swallowed a dragon.
A small one, sure, but now his arms are growing scales, the local wildlife is acting up, and his snarky AI familiar is no help whatsoever.
Raven's best friend Aik is a guardsman carrying a torch for the thief. A pickpocket and a guard? Never going to happen. And Aik's ex-fiancé Silya, an initiate priestess in the midst of a magical crisis, hates Raven with the heat of a thousand suns.
This unlikely team must work together to face strange beasts, alien artifacts, and a world-altering threat. If they don't figure out what to do soon, it might just be the end of everything.
Things are about to get messy.
