I've never read Jay Lake before, but I've heard a lot about him, and this book looks incredible. The writing in the first chapter is very deliberate, squeezing in tons of information without making it an overload.
It's about a girl who doesn't remember her name, who is sold by her father to become a courtesan and an assassin. That right there is all I need to go holy crap I need to read this! There is also magic in this book, and gods who meddle with people (think Greek myth).
