Enough with Romeo and Juliet, enough with 'near-pornography'! The fact that this is a tragedy reminiscent of Shakespeare is used as a contrast of R&J, not a retelling.
Its flaws are of logical plot turns and character, not a misplacement in the young adult genre. It IS a young adult novel, written about a boy and girl more realistic, perhaps, than parents would like their children to read about, but it is far from pornographic (look in your school libraries for Tropic of Cancer and Ulysses if you want something to get angry about). Much is said here about Chapter 6, but what of Chapter 13? Is sex so much worse than an innocent's death? Young people read more graphic things in Cosmo and the Bible.
This novel is about powerlessness and self-doubt in the face of Fate, and in that it succeeds better than most.
