Although, this book is described as not yet released, it has been published under the title "The Book of the Dead". I would guess that, as some other authors have done, it is being released in the USA under the new title. Beware, before you pre order it!
I have read the description on amazon and on waterstones online and they are the same, the release dates are different though. I checked other websites too and all the same. This is a brand new story indeed, this and the title `Book of the Dead' are not the same. Though do check with a reputable book company of the release date.
I agree with above Post. Book of the Dead and Scarpetta are two different books. I have read them both, just finished reading Scarpetta, it was quite good, not as good as her first books, better though than her last ones though
