Ximena is the decoy Condesa, a stand-in for the last remaining Illustrian royal. Her people lost everything when the usurper, Atoc, used an ancient relic to summon ghosts and drive the Illustrians from La Ciudad. Now Ximena's motivated by her insatiable thirst for revenge, and her rare ability to spin thread from moonlight. When Atoc demands the real Condesa's hand in marriage, it's Ximena's duty to go in her stead. Using the opportunity to get close to Atoc, she can steal his relic and return the true aristócrata to their rightful place. But a masked vigilante, a warm-hearted princess, and a thoughtful healer challenge Ximena, and her mission becomes more complicated. There could be a way to overthrow the usurper without starting another war, but only if Ximena turns her back on revenge-and her Condesa.
