Andrew Britton continues on a roll with his third novel, “The Invisible.” After his debut novel, “The American,” was a success (Britton wrote it when he was only 21), he was since produced a sophomore effort, “The Assassin,” which also was a success. In the new book, the central character continues to be CIA agent Ryan Healey. This time, Healey is wandering the world after being dumped by his girlfriend and fellow agent, Naomi Kharmai. But when he has a chance to win her back, he accepts an assignment to track down an assassin who has kidnapped several Americans in Pakistan. Complications — as well as explosions — will ensue. Think of Britton as a modern updating of Robert Ludlum or John le Carre.

As usual, there is a bevy of nonfiction (which outsells fiction about 9 to 1, according to estimates I’ve seen) and as usual, a lot of it is about war. In “Roll Call To Destiny,” Brent Nosworthy looks at Civil War battles through the eyes of the front line soldiers. And in “The Complex,” Nick Turse offers some scary examples of how the military “invades our everyday lives.” For example, Turse explains that many of the products you use every day — from toothpaste to the television network you watch — are contractors with the military and benefit with expanded military action. He proposes that the “military-industrial complex” actually be called “the military-industrial-technological-entertainment-scientific-media-corporate complex.” Thanks, we’ll all sleep better for knowing that, eh?
