Eris has been held prisoner since the attack on the capital city, which almost killed her. And she begins to wish it had when she discovers Sona—the girl she loves, the girl she would tear down cities for—also survived, only to be captured and corrupted by the Zenith.

Their last hope for victory will depend on whether Eris and Sona can somehow find their way back to each other from opposite sides of a war...
