An Ember of Ashes by Sabaa Tahir
"Laia is a slave. Elias is a soldier. Neither is free. Under the Martial Empire, defiance is met with death. Those who do not vow their blood and bodies to the Emperor risk the execution of their loved ones and the destruction of all they hold dear. It is in this brutal world, inspired by ancient Rome, that Laia lives with her grandparents and older brother. The family ekes out an existence in the Empire's impoverished backstreets. They do not challenge the Empire. They've seen what happens to those who do. But when Laia's brother is arrested for treason, Laia is forced to make a decision. In exchange for help from rebels who promise to rescue her brother, she will risk her life to spy for them from within the Empire's greatest military academy. There, Laia meets Elias, the school's finest soldier--and secretly, its most unwilling. Elias wants only to be free of the tyranny he's being trained to enforce. He and Laia will soon realize that their destinies are intertwined--and that their choices will change the fate of the Empire itself."

When a vicious attack by Anglion's ancient enemies leaves the kingdom in chaos, Sophia is forced to flee the court. Her protector by happenstance is Lieutenant Cameron Mackenzie, a member of the royal guard, raised all his life to be fiercely loyal to the Crown. Then Sophia's powers manifest stronger than she ever imagined they would, and Cameron and she are inextricably linked in the process. As a witch unbound by marriage rites, Sophia is not only a threat to the established order of her country, but is also a weapon for those who seek to destroy it. Faced with old secrets and new truths, she must decide if she will fight for her country or succumb to the delicious temptation of power...."
