"This novel is a harrowing, haunting reminder of what it means to be human--and how hope might be kindled in the midst of oppression and fear." -- The Washington Post

The beloved and bestselling fantasy series that "glows, burns, and smolders." (Huffington Post).

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.
