I agree with the previous reviewer that this was a long anticipated book.
After the ending of L.A. Requiem there was a fear that Crais was retiring Elvis and Joe. However his fans are rewarded with another superbly crafted work.
The character development continues and you learn more about Cole and discover that Pike may no longer be the superman he seemed to be. Crais has also woven in his heroine, Starkey, from Demolition Angel to add to the pot.
For those fans of Michael Connelly we also get a homage to his Heironymous Bosch character. Thankfully this is far better done than the high tech thrillers where they just say "it was just like something from a Brown/Clancy/Bond book". Unless you know the character you'll miss the link.
The story zips along and you won't want to stop reading. The story alternates between the viewpoint of Cole, Pike and Ben. The plot is believeable and never relents. You hate the breakdown of his relationship with the boy's mother and hope that it will survive.
Like Connelly he breathes life into an L.A. that every knows, even if they've never been there. However just one word of warning. There are 7 previous Cole/Pike stories and not 4. I recommend that you read them all before starting this.
For those who read Crais for the first time you don't know what you've missed. You WILL want to read more.
