Now free, with a misfit army of rebels to back her, Theo must liberate her enslaved people. But though the Kaiser is dead, Theo now faces an even more terrifying enemy who has risen in his place: the new Kaiserin. Imbued with a magic no one understands, the Kaiserin is determined to burn down anyone and everything in her way.
The Kaiserin' s strange power is growing stronger, and with Prinz Søren as her hostage, there is more at stake than ever. Theo must learn to embrace her own power if she has any hope of standing against the girl she once called her heart' s sister.
