<p>As others have suggested, thrillers may be good-- John Sanford, Lee Child, Dan Brown, Jeffrey Deaver. As a teen I liked Kurt Vonnegut a lot; though my daughter didn’t. If he likes Jon Krakauer, then others in that non-fiction vein are “Devil in the White City”, “Isaac’s Storm”, “Endurance”, “In the Heart of the Sea”, “Perfect Storm”. All of those, while true, may be classified as “thrillers”. </p>
<p>The Game of Thrones series is a good suggestion (my son devoured those at that age). But be warned, they are full of sex and violence (or so I’m told anyway). I’m a libertarian when it comes to what my kids read, but other parents may not be the same.</p>
