The Oracle fears what else may be hidden in the halls and walls of Rosehill. The Tailor is trapped in the demimonde. The Curator knows the way forward means pain and blood. As barriers break between reality and other realms, and alliances crack and form anew, Calix, Ethaniel, and Aubrey know they cannot survive the horrors beset upon them alone. Magnus, Aubrey's mentor and the Head Curator of the Magnificus Collectio, is a powerful mage but even he knows the demimonde is not a place to tread if you're mortal. Enlisting the help of a very old (and rather odd) colleague means revealing secrets he'd kept for so long. And placing that colleague in the direct line of danger surfaces more than mere guilt. Ethaniel's fate lies in all their hands... but Uzala, the Mapmaker, has plans of their own. A Harkness in the demimonde is a unique opportunity, and one it will not squander. And while the race to bring Ethaniel back traps them all once more in the walls of Rosehill, Aubrey's chance to prove himself brings up uncomfortable-and perhaps deadly-family secrets and parts of his past that he has no intention of speaking aloud. But like always, magic and the demimonde have other plans. Lawton is caught in his own inner turmoil, but the Golden Order is still searching for him. And he is still harboring the malingering spirit of Calix's mother, Lily. His fate has always been tied to Calix, but now he has the chance to understand who he is, and who he could become. In the final book of the Oracle, Tailor, Curator trilogy, danger is faced head-on, vows to protect are fortified, and the lives of more then the trio are at stake. Their world, and their understanding of magic, will never be the same.
