The greatest treasure, a most dangerous magic.

Growing up in the Cinzio Traveling Players Company, Genevieve Flannery is accustomed to a life most teenagers could never imagine: daily workouts of extravagant acrobatics; wild animals for pets; and her mother, Delia, whose mind has always been tortured by visions—but whose love Geni never questions. In a world of performers who mystify and amaze on a daily basis, Delia's ghostly hallucinations never seemed all that strange . . . until the evening Geni and her mother are performing an aerial routine they've done hundreds of times, and Delia falls to her death.

That night, a dark curtain in Geni's life opens. Everything has changed.

As they reel from the tragedy, the Cinzio Players are also grappling with the circus's new owner: a generous, mysterious man whose connection to the circus—Geni suspects—has a dark history. And with the discovery of an otherworldly inheritance and her perilous mission to protect it, Geni is suddenly stumbling into a new reality of her own, her life interrupted daily by the terrors only Delia used to see. As the visions around her grow stronger, and her magical legacy becomes even more menacing, Geni is not sure who she should trust or love. Worst of all, she's starting to question whether she can trust her own mind.
