One that comes to mind is John Wyndham's The Chrysalids - a post-nuclear dystopia that is perfect for adolescents (or was for me, anyway) because it expresses the feeling of being an isolated mutant. Eventually the isolated mutant kids find each other, band together, and defeat the dysfunctional authorities. That was profoundly satisfying when I was 14 or whenever I read it.

Same author, another mind blowing book, especially then: " Day of the Triffids". one of the first apocalypse books. Makes you always think twice when looking up at the Aurora Borealis, like a few days ago.
