Quinn is a 'cleaner' - a guy that sorts the mess other people leave behind, usually the disposal of bodies and the cleaning up of assorted mayhem. This is the third book in the 'cleaner' series and has many themes that fans of Robert Ludlum's Jason Bourne would recognise: highly skilled operatives, shadowy organisations within Government, conspiracy and a lot of action.
In this story, a UN worker and the child she is protecting are being hunted and Quinn and his small team need to find her and understand what is going on. Cue car chases, gunfights and mysterious bad guys.
Actually I like Quinn and the author does weave a fast paced story, while actually trying for character development so that Quinn and his chums do change over the novels and evolve with their experiences and relationships. This is fast moving and easy reading, I finished it in two days, having fallen into the 'just one more chapter' trap and then finding it was 2am!
That is not to say this is not flawed, the plot that Quinn ends up trying to stop is a bit convoluted and there are elements that could have perhaps been better resolved (probably setting things up for the next book) in a climax that was a little abrupt. But having said that, it is a fast moving thriller that fans of the series will enjoy. If you are new to the series, then I would suggest you start with the first one, "The Cleaner".
