Hush

"From perfect cold, dark and silent, the world has flickered. Now it sputters; soon it fades. The hush of an unending winter night is the only true eternity." 

Infidel must journey to the frozen north to return a sacred relic to an ogre temple. She hires the Freewind, helmed by Captain Gale Romer, to make the perilous journey. But when the Freewind is attacked by fanatical cultists, Infidel finds herself caught up in a battle between primal dragons as Hush, the dragon of cold, tries to kill Glorious, the dragon of the sun, to plunge the world into unending winter.

Opening lines:

A princess, a shape-shifter, and a ghost walked into a bar.

The room fell silent as all eyes turned toward the princess. The bar was the Black Swan, the most prestigious saloon in Commonground. While the house wasn't as packed as it would be come midnight, scores of hardcore gamblers crowded around the poker tables. Ordinarily, you could march a two-headed tiger through the joint and the players wouldn't glance up from their cards. The gamblers made an exception for the princess, known in these parts as Infidel, who was much more dangerous than a tiger no matter how many heads it might have.
