I saw this reviewed well in the Guardian and bought it. Nothing wrong with the plot outline: renaissance society in a timeless 'Venice' is changed through the influence of genetically modified human slaves brought in from a foreign state. Church and tradition regard the genics as sub-human, how will four of them find their places in this water-lapped city? I got inreasingly fed-up, though, with the over simplifications running through the book. The evil count - Count Dracone, puhleese - is nothing but a cypher trafficking with devils, all that is needed to deal with his machinations is faith, and all the presumably deep-ingrained prejudice against the genics is smoothly washed away by a few people speaking out against it. For me, the bones of a good story, but lacking shades of grey and enough character detail to believe in them.
