Not sure if you want suggestions that are not thriller/urban fantasy-type stories. For teens that are more mature and want "thinking" stories but aren't too girly in their approach, Jan Mark's "The Eclipse of the Century" and "Useful Idiots" are superb (weird but pretty advanced in their plots), her "Stratford Boys" is a funny look at how a young Will Shakespeare and his gang of teen mates put on their first play.
Mal Peet's Tamar is set in WW2 about undercover SOE agents (but there is a significant romantic plotline).
Aidan Chambers - any of his books are good for older teens, but they're about issues in modern life - relationships, death, sexuality, identity, religion - and not plot-rich thrillers.
New World Order by Ben Jeapes sets time-travelling folk from our future back into the English Civil War and using hi-tech weaponry to advance the cause of King or Cromwell.
I wasn't impressed by Hatchet, myself, as the scenarios were a little over-egged; but a good wilderness story that all of my kids loved to bits (until the book dropped to bits) was My Side of the Mountain by Jean George.
One of my 14/15 yr olds has this week been reading The Bridge Over the River Kwai, some of the original Planet of the Apes novelisations (ready for the new film next year), the book of the film Dog Day Afternoon and Brighton Rock by Graham Greene.
The Godfather is a big hit with our teens too.
