It's a good thriller, but it's not a great Elvis Cole book.
As the series has progressed, Crais has kept on raising the physical and emotional stakes for his protagonists. Early on in the series, bad things happen to strangers and clients. Then bad things happen to people close to the main characters. Then bad things happen to the heroes directly. By now, it's almost impossible to conceive of an Elvis Cole/Joe Pike story where the two of them are not in mortal danger on every page.
It gets tiring.
Cole still jokes about being the World's Greatest Detective, but his heart isn't in it any more. He feels tired and broken, and, well, not much fun
Joe Pike has always been a darker character, and I'm happy enough reading a grim tale with him at the centre. But I much prefer the easy-going Elvis Cole from from back in [b:The Monkey's Raincoat|14404|The Monkey's Raincoat (Elvis Cole, #1)|Robert Crais|http://d.gr-assets.com/books/1348618089s/14404.jpg|2541445] or [b:Indigo Slam|241933|Indigo Slam (Elvis Cole, #7)|Robert Crais|http://d.gr-assets.com/books/1320434242s/241933.jpg|2667420].
