"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"--Provided by publisher.
