I picked this up on a whim, and am so glad I did. I really enjoyed it.
Locke is a thief, a conman, a liar, with his small gang of "gentleman bastards" they happily prey on the nobility of the faux Venice, Camorr, and decieve the criminal overlord. Then one day they encounter the grey king, who is killing off the thieves loyal to their master.

This is a pleasant change from fantasy quest novels, you actually care about the characters whether you like them or not, you want to see what happens and why. You want Locke to win, whether it's his latest con or the plot that dominates the second half of the novel (I don't want to spoil it because it's worth it)
With a hundred pages left I rushed out and bought Red Seas under Red Skies because I absolutely HAD to know what happened next.
Here's hoping it's half as good, because even then, it's much better than what I've been reading lately.
