This is a YA fantasy, but what struck me is that it's not written like a lot of the current YA offerings. It's very close to an adult fantasy in style, just pared down and faster to read. 
 Widdershins is a thief. She had been a member of Society, a real rags to riches story. When she witnesses the horrific massacre of her friends, she escapes, melting into the criminal underworld of her youth. Years later old enemies try to snuff her out, making her re-examine her past. There's a complex pantheon of gods and I liked how that was used here, especially in terms of Widdershins unseen "friend." 
 The narrative bounces around in time as we learn about her past and present, but it wasn't hard to follow. 
 There is violence, no romance. I liked the characters and wish that there had been more time with some of them. That's what puts this one in the YA category, I think, that it is short. Very quick, but still tells the tale. I'll be checking out the next one.
