From New York Times bestselling author Roshani Chokshi comes a novel set in Paris during a time of extraordinary change—one that is full of mystery, decadence, and dangerous desires... It's 1889. The city is on the cusp of industry and power, and the Exposition Universelle has breathed new life into the streets and dredged up ancient secrets. Here, no one keeps tabs on dark truths better than treasure-hunter and wealthy hotelier Séverin Montagnet-Alarie. When the elite, ever-powerful Order of Babel coerces him to help them on a mission, Séverin is offered a treasure that he never imagined: his true inheritance. To hunt down the ancient artifact the Order seeks, Séverin calls upon a band of unlikely experts: An engineer with a debt to pay. A historian banished from his home. A dancer with a sinister past. And a brother in arms if not blood. Together, they will join Séverin as he explores the dark, glittering heart of Paris. What they find might change the course of history—but only if they can stay alive.

They are each other's fiercest love, greatest danger, and only hope. Séverin and his team members might have successfully thwarted the Fallen House, but victory came at a terrible cost—one that still haunts all of them. Desperate to make amends, Séverin pursues a dangerous lead to find a long lost artifact rumoured to grant its possessor the power of God. Their hunt lures them far from Paris, and into the icy heart of Russia where crystalline ice animals stalk forgotten mansions, broken goddesses carry deadly secrets, and a string of unsolved murders makes the crew question whether an ancient myth is a myth after all. As hidden secrets come to the light and the ghosts of the past catch up to them, the crew will discover new dimensions of themselves. But what they find out may lead them down paths they never imagined. A tale of love and betrayal as the crew risks their lives for one last job.

In love they breathed. In destiny they believed. In the end, will divinity be their demise? After Séverin's seeming betrayal, the crew is fractured. Armed with only a handful of hints, Enrique, Laila, Hypnos and Zofia must find their way through the snarled, haunted waterways of Venice, Italy to locate Séverin. Meanwhile, Séverin must balance the deranged whims of the Patriarch of the Fallen House and discover the location of a temple beneath a plague island where the Divine Lyre can be played and all that he desires will come to pass. With only ten days until Laila expires, the crew will face plague pits and deadly masquerades, unearthly songs and the shining steps of a temple whose powers might offer divinity itself... but at a price they may not be willing to pay. Returning to the dark and glamorous 19th century world of her New York Times instant bestseller, The Gilded Wolves, Roshani Chokshi dazzles us with the final riveting tale as full of mystery and danger as ever.
