Aurelian cycle

Annie and Lee were only children when revolution changed their world. Now they are both rising stars in the new regime. But everything changes when survivors from the old regime surface, bent on reclaiming their city. With war on the horizon, Lee must chose to kill the only family he has left or to betray everything he's come to believe in. And Annie must decide whether to protect her dearest friend or step up to be the champion her city needs.

"Annie and Lee are fighting for their lives--and for each other--as invading dragonfire threatens to burn their home to the ground"--
