My Take

Mark Greaney is the kind of thriller writer who makes you feel like you've been handed classified intel — his Gray Man series starring Court Gentry, the freelance assassin with a conscience, is genuinely one of the more compulsively readable action franchises of the past two decades. What impresses me most is that Greaney did his homework: before putting pen to paper he reportedly traveled extensively and researched real tradecraft, and it shows in every chase sequence and covert op. He also stepped into an almost impossible role as the heir to Tom Clancy's Ryanverse, and rather than fumbling it, he kept the machinery humming with clear-eyed geopolitical plotting. A Memphis kid who built a career out of knowing where every gunman in the room would be standing — that's a pretty solid legacy.
