First was Rucka's The Last Run. It's not a return to the Atticus Kodiak cycle, though his last book was. Instead, this is the third Queen & Country novel, the same series that started as a comic I mentioned before. In fact, the comic returned for a while after the last novel, Private Wars, came out in 2005. I do not own those issues in any form, something I should rectify.
The new novel begins with Tara Chace feeling like it's time to stop being a Minder. Events, of course, conspire to keep her active for one last mission involving double crosses and politics in Iran. Back home, her boss Paul Crocker is dealing with political repercussions from his utter support of his Minders over the years. It's fast-paced and very engrossing and I loved every minute of it. I did see the ending coming but I was okay with it, as it puts a pin on the series.
Speaking of putting a pin on a series, Lehane's Moonlight Mile is his first Kenzie and Gennaro novel since 1999's Prayers For Rain. The new one actually deals with events from Gone Baby Gone, which was released the year prior to Prayers For Rain (and made into a critically-acclaimed movie by Ben Affleck that I still haven't seen). Amanda McCready, the kidnapped girl from that book, has once more disappeared. Kenzie and Gennaro are now married with a four year-old daughter, barely holding on in the down economy and find themselves drawn back into Amanda's life. It's a compelling book that deals with guilt and class issues and the big issue of right versus wrong. I read it quickly. Unfortunately, I don't think there will be another one but I'm okay with the way it ended.
If you like your PI/bodyguard genre, you could do worse than picking up some Rucka or Lehane. I'd start at the beginning, though. You won't be able to stop yourself from catching up quickly.
