The favorites books of teenagers

Today, I asked to 30 teenagers this question: What is your favorite book? And I understood that the modern teenagers don't like to read. I think it's very sad, because the books are a real masterpiece and they make what we are. So, if I understand correctly my result, the boys don't know how to read.

I'll give you examples of my answers.

Harry Potter: 2 teenagers/30
Arielle Queen: 2/30
Amos Daragon: 1/30
Les loups du tsar: 1/30
L'apprenti d'araluen: 2/30
Un cadavre de luxe: 1/30
Âme vagabonde: 2/30
Twilight: 2/30
Aurélie Laflamme: 2/30
Rouge poison: 1/30
Les fourmis: 1/30
nothing, I don't know how to read: 8/30
