First half: meh.
Second half: HOLY SHIIIIIIIII-

3.5 ? I feel bad giving a mark because.. I didn't read it properly.
The beginning didn't pull me in enough and I started hearing without really listening (audio book problems). I wasn't caring about much for quite a while but...
Then I finally got into it.
I loved how dark and gritty it was. I started getting attached to the characters.

I'd go for the 2d book if it were out now but it isn't. And by the time it actually comes out, I'm pretty sure I will have forgotten most of what happened...
