Okay, here's some serious ass-kicking books you may have overlooked. They're written by buddies of mine, which made me all the more relieved when they were really good.
The Purification Ceremony, by Mark T. Sullivan. I met Mark at Thrillerfest this year, and got a copy of this tracker-in-the-woods thriller. Not only does he know this world inside-out, but his prose is goddamned beautiful. I mean, this boy can seriously write.
Shotgun Alley, by Andrew Klavan. The second in Drew's superb Weiss and Bishop series (or, as I like to think of it, Bishop and Weiss series), this is a great, wonderfully written story about outlaw biker gangs. It was interesting to see what a writer who I admire did with the same world I researched for Troubleshooter. (Drew's latest, Damnation Alley - also great - just came out).
Public Enemy, by Will Staeger. Okay, so I'm cheating because I'm not quite done yet. But Will is such a solid writer that I know the ending will be great. When I blurbed his first book, I referred to his "adrenalized lyricism" and that's precisely what it is.
These books are remarkably different, but they all have excellent crime/action plots and ALSO (increasingly rare) wonderful use of language. These are three novelists who aren't just storytellers, they're writers too. Check out three guys at the top of their game.
