Burningblade and Silvereye

Long ago, a magical war destroyed an empire and a new one was built in its ashes. But still the old grudges simmer and two siblings will fight on opposite sides to save their world in the start of Django Wexler's new epic fantasy trilogy. Gyre hasn't seen his beloved sister since their parents sold her to the mysterious Twilight Order. Now, 12 years after her disappearance, Gyre's sole focus is revenge and he's willing to risk anything and anyone to claim enough power to destroy the Order. 

Four hundred years ago, a cataclysmic war cracked the world open and exterminated the Elder races. Amid the ashes, their human inheritor, the Dawn Republic, stands guard over lands littered with eldritch relics and cursed by plaguespawn outbreaks. But a new conflict is looming, and brother and sister Maya and Gyre have found themselves on opposite sides. 

The last surviving Chosen, Ashok, has finally risen up and taken control of The Twilight Order. He promises equality and prosperity, but Gyre and Maya know the truth. Only death follows in Ashok's wake. To take him down, Gyre will have to unite old allies—from all across The Splinter Kingdoms and the depths of Deepfire. And Maya will have to seek out a legendary weapon hidden in the mountains that could turn the tide in their battle for freedom.
