Jay Lake's "The Trial of Flowers" is a decadent, dark urban fantasy in the mold of M. John Harrison's "Viriconium" or, as the book's jacket mentions, "Perdido Street Station" and "The Etched City".
The City Imperishable is a sprawling, ancient metropolis where power rests in the hands of the rich and the city's dwarves are treated like second class citizens. It immediately brings to mind an industrializing London layered with Rome at its darkest and most decayed. The Cthuluesque old gods are awakening and terrorizing the city by offing its citizens in dark and bloody ways during the night. The heir to the long vacant throne disappears early in the book, and a combined army of barbarian tribes is on the march with the intention of pulling the city down brick by brick so that its long dead but still feared empire will never rise again.
Into this swirling and bloody backdrop are cast the three main characters: Jason, servant and friend of the missing heir; Bijaz the Dwarf, leader of the city's sewn dwarves, whose lips are gruesomely sealed; and Imago, a down in his luck lawyer of sorts with an ingenious plan to reinstate the office of the mayor by staging "the trial of flowers", a rite so ancient that no one knows what it is.
These three uneasy allies are ultimately tasked with saving the city, journeying through the drug dens, torture pits, and ancient temples beneath the city and into the dark, magic filled nights on a quest to stop the resurrection of terrible gods who derive their power from bloodshed and suffering.
Lake's decadent world is ripe with decay, corruption, violence and sex. A world well worth visiting.
