Wisteria is the conclusion to the Belladonna trilogy. I'm not going to lie I was not fully looking forward to this book because I knew fate who I have not enjoyed at all was going to be one of the main focuses of the book. Having said that though after I got about a quarter into it and we see Blythe and Fate having to start dealing with each other more and we see Blythe start standing on her own more I enjoyed the book more and more. 
Blythe is a very strong character, and while not surprising I wasn't sure she was going to be able to do all that she did. Then when she finally figured out the true extent of what she could do things really take off and the rest of the story goes by so fast due to fate and death bickering, and fate and Blythe bickering. While all this bickering might get old for some people for me it worked because I loved the banter between all of these characters and the way they were able to get under each others skin while still showing that they cared about the other one. 

Overall this was a good conclusion to the story. 

P.S. Death is still my favorite character.
