"Mantén a tus enemigos cerca"--Cover

After rescuing her sister, Olivia, from imprisonment in Lera, a rival kingdom, Em has 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. 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 take the throne, Em believes a truce is within reach. But when winning the war could mean betraying her family, she 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.--
