This is very depressing... I think there's so much poor literature around that it's hard to find the gems (like Wildwood, as a PP mentioned) and schools are certainly not helping... My eldest DD (now 13) gravitated towards the classics by late primary school- absolutely loved greek myths and read Homer's Illiad and Odyssey at 11y/o, but now at high school the literature they're studying is so poor that she's become quite disenchanted by studying literature at all, and will now just re-read her old favourite books rather than tackle something new. If anyone has any suggestions for great literature/ literary gems suitable for a teen, that'd be great!
