I think most of my issue with this book stemmed from not knowing where the hell the Fetch came from and what its purpose was. Outside of just being an 'omen' of death... why was May around?? Why would the world create a copy of a person just to show them that if they stick on their current path they are gonna die? I've finished the whole book and I STILL don't know the reason May was there, other than marking off yet another month that Seanan McGuire has used as a name. (Pretty sure I read a comment about that in the book too; something about what was she gonna do when all the months were used up...I'm taking a wild guess and saying she'll go with days of the week, or periodic table elements) *Pokes out her eyes* 
 Everything that May did for Toby could have been done by someone else. I can only imagine its going to be answered in subsequent books as to why it had to be a Fetch, and what a Fetch really does. Well.. we can hope. 
 If not, I guess its just one of those things I'll continue to pull my hair out about. 
 All in all, the plot moved MUCH faster in this book compared to her last one. Blind Michael was a great villian. It was good to see Toby's friends come out of the woodwork to help her out. 
 I'm looking forward to seeing if my questions are answered in the next installment!
