Mike Wrecker has finally ended the life of the man who killed his girlfriend, but that also means he's now alerted his former employers at the CIA that he's a problem that remains a loose end. In other words, the folks who run the Centurion program, who used to run him, want to kill him. And they're very good at killing. In "Blowback," author Mike Ryan brings in a lot more intrigue and high suspense than his previous novels in the series. He introduces several characters from the CIA and finally explains Wrecker's back story. He also further explains the motivations behind Wrecker's fall from grace in the Centurion program, basically why his employers decided to kill him and send Agent 17 to snuff out his girlfriend. And, of course, Ryan does it without spending a whole lot of time on tangential story lines or drama or mind-numbing detail. He gets to the action. This was my favorite of the series so far. I enjoyed the new character, especially the woman from the agency who is tasked with either killing him or bringing him in.
