The Lies of Locke Lamora by Scott Lynch
There was lots to like since I always find heists to be great fun (/begin long aside not that you would have known from the fact that I don't review very many but I do in fact enjoy heist books just that there don't seem to be a whole lot in the fantasy genre perhaps or I haven't actively sought them out or some such thing /end long aside).
Locke is a splashy character and the learning to be a special kind of thief is reminiscent of Take a Thief by Mercedes Lackey but more for adults, and the storyline in some ways are quite similar. Jean is great to follow as well, and I like that he names his weapons. The reveals are lots of fun.
This is the author's first offering, and it is quite good. There is a second book out already. This series is meant to be 7 books long although there has been a very long hang-up for the writing of book 3 due to depression issues of the author.
