The Exiled Blade — Jon Courtenay Grimwood

Snow shrouds Venice in cold darkness, ice fills the canals, and a thousand ghosts pluck at the shadow's edge.

A violent attack on Lady Giulietta's son forces Tycho from his new-found happiness and back into the treacherous intrigue of the court. For Giulietta's sake he would go to the world's end to track down those responsible.

As Venice teeters on the brink of civil war, its warring families prepare to discover who is a player and who a pawn in the coming struggle for power.

The Exiled Blade is the climatic finale to Tycho's story.
