It's rare. I give up on a book and don't finish reading it..... But this book failed to grip me from page 1. I had read the intro that had explained the dramatic devise of telling the end first and then working backwards. The intro also explained how the characters are only faintly outlined at first and are fleshed out as the book goes on. 

So, having not enjoyed the first couple of pages, I wondered if reading it in reverse would help. I thought the more developed characters might be more interesting. (The book is divided into sub books. Latest first, earliest last). I turned to the last book and tried again, but after 2 pages I just didn't care enough about any character in the story and stopped reading. Not recommended at all!!
