Am I to young to read The Perks of Being A Wallflower?

you're definitely NOT too young to read it. i'm fifteen, and i read it when i was thirteen. there's some mature content, but it's probably nothing you haven't heard before. if you're wondering, there's a fair amount of drug content and a bit of ual stuff. but overall, it's definitely worth the read (it's my favourite book) and you shouldn't worry about the content. if it makes you uncomfortable, you can always stop!
