@JSWolf: I love Flynn! Mitch Rapp is the man. I can't believe I failed to include him.
Funny story about Flynn--My dad is not much of a reader, but he was having trouble falling asleep, so I gave him Flynn's first Mitch Rapp book, and my mom called a few weeks later to say that he was loving it. When I visited the next summer, the book was on his night stand with a bookmark about 1/3 of the way in. I said, "I thought you loved it." He said, "I do! It's great!" My mom said, "He reads a page a night and then falls fast asleep!" So our family has decided to get him about two more books, as that should last him for the rest of his life.
