Oath Breaker

Bound by a blood oath and harboring a deadly secret, she's out of time.
Avarielle Grayloft has survived two wars, the loss of family, and a battle against an ancient god. Her magical blade has sliced through monsters and gods alike, and she's no stranger to the tang of her own blood. But that blood runs cold when monsters return to her land after twenty years of peace.
Desperate to protect her son and her home, Avarielle reaches out to old allies for help: the most powerful queen in Graydon, and its highest-ranking sorceress. Together, the three women defeated the monsters once before, and Avarielle hopes they can do so again.
But Avarielle and her allies are not who they once were. The price they paid for their power was steep, and now they are linked by a dark secret forged in the blood of a god...a secret so deadly that it could shatter their world. And them.
Will their remaining magic be enough to stop the return of evil? Or has too much time passed and too much of their power already been lost?
Twenty years ago, they became legends by saving the lands. But their actions had consequences far beyond the battlefield, and now it's time to pay the price for their victory.
This series takes place twenty years after Heirs of a Broken Land and features some of the same characters, but you can easily enter the lands of Graydon and Elihor via this series. Follow your reading heart!
