The worst book you have read

[Albertosaurus Rex]

Disturbing how exactly...? (It's okay if you don't want to recall it. I have no intention of traumatising you all over again.)

furthermore, the protagonist and his, lets call it, girlfriend are both barely 14, and there is no cultural excuse in this one and they're so naive that it's just disgusting.

While I do think 14 is too young, the fact is that it happens. Why shouldn't a novel deal with that? (Of course, it does matter a great deal how the novel handled it.) I mean, as far as I know most readers of A Song of Ice and Fire don't approve of incest, but it doesn't stop them from the reading the novels.
