A war that will fuel her. A bond that will destroy her.

Emelina Flores has come home to Ruina. After rescuing her sister Olivia from imprisonment in rival kingdom Lera, Em and Olivia together have devised a plan that will rebuild Ruina to its former glory.

But just because Em and Olivia are out of Lera doesn't mean they are safe. Their actions over the past year have had consequences, and they are now targets of retaliation. Olivia will destroy everyone who acts against Ruina, but Em isn't as sure.

Ever since Em posed as Prince Casimir's betrothed in Lera, she's started to see another side to this war. Lera may have destroyed the Ruined for decades, but Em knows that Cas is different. And now that he's taken the throne, Em believes a truce is within reach. But Olivia suspects that Em's romantic feelings for Cas are just colouring her judgement.

Em is determined to bring peace to her home. But when winning the war could mean betraying her family, Em faces an impossible choice between loyalty and love. Em must stay one step ahead of her enemies—and her blood—before she's the next victim in this battle for sovereignty.
