Of Blood and Fire by Keri Arthur

Can an improbable alliance between human and drakkon save their world from utter destruction?

Princess Bryn Silva never wanted the crown this way.
With her parents dead and Esan’s military devastated, she’s thrust onto a throne she once wanted, but is utterly unprepared to fill.
Worse still, her husband, Damon—heir to the throne of Zephrine—has vanished, leaving her to face the storm alone.
As the gilded riders, hungry to claim Arleeon’s fertile lands as their own, rain death and destruction from their armored birds, the greatest threat to both Bryn and Esan might come from the one man who should be their staunchest ally.
Because Aric Velez—Damon’s father—has returned, and plans to use her inexperience to claim the throne and become the ultimate ruler over all Arleeon. And he doesn’t care what he has to do to see his ambitions realized.

As the losses mount, the race to find a means of defeating their foes becomes ever more desperate. But can the drakkon kin ever hope to win a war when they are so outnumbered?

Or will Bryn be forced to face an impossible choice: sacrifice everything she loves, or watch her kingdom burn.
