I loved this book's plot and this original idea of the story which was set in the UK and where instead of prisoners going to jail, they are placed in the custody of the victim who has to become their jailor. I found the writing of the book very interesting and easy to follow and from the very beginning it intrigued me a lot. This book was full of twists which made me shook but I think that some things were a bit predictable such as Hannah's and Jem's relationship or Rupert being the killer (maybe it was before I've read lots of crime books with the same storyline about how the characters turn to be, before in some way). Also I think that after the first half of the book (after Hannah's and Jem's attempt to escape) some things starting kind of rushing up and happening very quickly which annoyed me a bit. However, I still enjoyed this greatly and I'm very with the ending except of one thing! We never get to know what happens to Mr Dalgleish!
