To be born a slave is in fact not a fatality. And facts can be changed. In the country of Ossaniul, there is a fortress that is as disproportionate as it is inaccessible: the Highest House. Its masters, the noble family of Aldercrest, reign over a veritable army of slaves. At the bottom of the ladder, young Moth performs the most thankless tasks and has little hope of living past childhood. Until the day he meets Obsidian, a mysterious prisoner of the House who whispers to him in his sleep. If Moth does what he asks, Obsidian will give him fortune and glory. And there's every indication that Obsidian can make good on his promises. Will Moth accept the offer? Through a subtle alternate history, The Highest House takes us to a fictional country reminiscent of the Balkan kingdoms of the 16th century. Mike Carey and Peter Gross (Lucifer, The Unwritten) draw from this context a captivating fantasy narrative that reflects on the human soul, the corrupting power of slavery, and the inequalities of class, all from the different perspectives of the House's many inhabitants. Both immediate and timeless, Highest House is a multifaceted fantasy sure to stay with readers long after the final page has turned.
