I think I would have given this book a even higher rating if I hadn't been listening to the audiobook, which makes me unable to skim. It lost a star for a few missteps of the "male writer writing female character" and the "white man writing minorities" sort. Also, the narrator of the audiobook... well... 
 The thing I liked best about this book (and there's a lot to like) is how much of an ass Lyda is. She is a truly unlikable person, but very compelling. She's flawed, and irritatingly self-absorbed, and above all she is COMPLICATED. A very well-written addict. 
 The world building was nice, a short jump into the future and a longing look at DIY drugs. I'll read more by the author for certain.
