A lot depends on the kid, methinks, but here's a few thoughts:
Both Charles Stross (Laundryverse) and John Scalzi can fit into the cynical-but-lighthearted mindset that appeals to plenty of teens.
Ryk Spoor has already pimped his books. I'd probably recommend Grand Central Arena first.
Dave Freer's Rats, Bats, and Vats.
Diplomatic Immunity by Lois Bujold, of course. But you have to start earlier. I imagine Elizabeth Bear also has some books that fit, but I can't give titles. Keeping It Real by Justina Robson.
