He's one I haven't read yet, but I mean to. I did get to hang out with him several times over the span of a weekend conference and he's absolutely the nicest guy. Completely lovely.
As a digression: what's great about his books:
- the variety of plots and settings; the early ones are all very distinct from each other.
- there's at least one really nifty bit of plotting in each. They're fairly light on the mystery elements compared to the thriller elements, but when there's a mystery it's a good one. "The Visitor" ("Running Blind" in the US I think), for example, is a superior serial-killer story - Child slipping in to the genre effortlessly.
- the protagonist. Reacher doesn't have many flaws, really - he's the toughest, the most cunning, the best shot, a super-sleuth - but Child writes him interestingly, and in fact writes him from either third and first person depending on which novel you pick up.
Recently I feel the first two of those have been stuttering a bit; we've seen a couple of books with very similar setups and settings, and Reacher tends to do a lot of driving around, which is a sign Lee is spinning his wheels I fear. (I sort of worry that he's publishing a little too often.) The first half of the most recent one was excellent, but then it rather faltered; so I'm hopeful for a return to form with the next.
