Devices and Desires (2005), Evil for Evil (2006) and The Escapement (2007) have all been very-well-reviewed, although I'm still a way behind on Parker. I enjoyed the Fencer Trilogy back when it was first released, but haven't picked up either the Scavenger or Engineer series. Parker's new novel, The Folding Knife, which is apparently a departure for her, is also published on 4 February in the UK and 22 February in the USA.
The blurb sounds most intriguing:
Basso the Magnificent. Basso the Great. Basso the Wise. Basso the Murderer. The First Citizen of the Vesani Republic is an extraordinary man. He is ruthless, cunning and, above all, lucky. He brings wealth, power and prestige to his people. But with power comes unwanted attention, and Basso must defend his nation and himself from threats foreign and domestic. In a lifetime of crucial decisions, he's only ever made one mistake. One mistake, though, can be enough.Very good. I'll have to rectify my lack of Parker reading this year, I think.
