Having had a quick look at other reviews I am convinced that there is no greater disservice you can do to a great book than have it placed on a school curriculum, it may be thought of as a tribute and recognition but it is the kiss of death to a work of the imagination particularly if the novel is about children. Inevitably it becomes a YA book and once that happens your novel is lost.
Fortunately I didn't go to school in New Zealand so I have only read this exceptionally fine novel recently. I also had the good fortune not to go to school in the USA so never had 'Catcher in the Rye' inflicted on me either but I can assure you that there is absolutely no comparison between the two, despite what numerous reviewers say, least of all in literary quality. This is an immensely better book and one that shows up the tawdry limits of that American classic.
Far too many people see this as a novel about the loss of innocence - it is the typical response when an author tackles a child coping with and being deceived by adult lies and evasions - rather than look at what such novels are really about - a child's attempts at understanding and how they are hampered by adults lack of courage when they are challenged - they retreat into a nostalgia over 'innocence' which really is only another name for ignorance - and the ignorant are always in the power of those who know the truth. Novels like this are novels of power - or rather powerlessness - throughout this heart breaking novel Jimmy Sullivan recounts his attempts to understand and to seek help and guidance from adults all of whom, parents, teachers, priests, retreat into cliches of a what a child must mean rather then listen to him.
This novel is set in a small town in New Zealand in the 1950's so can it still be relevant? it is pre television for goodness sakes! I would say yes because the desire of adults to lie to themselves by lying to children hasn't changed. Adults decide that children can't cope, need to be protected - the fatuity of the evasions that adults tell themselves are limitless - what they can't face up to is the challenge of a child recognising the lies being told them - but they do of course - and understanding brings maturity but also bitterness, hurt and betrayal. Information, truth doesn't corrupt or damage children, lies do.
I would rank this novel with 'Lord of the Flies' in the honesty of its portrayal of children and their struggle to comprehend but most particularly I would compare it to a completely undeservedly forgotten but brilliant novel 'The Kryptonite Kid' by Joseph Torchia - another tragic tale of a child destroyed by adult lies and evasions.
I can not praise this novel too highly - ignore the negative reviews and seek out this incredibly powerful and beautiful novel for a reading experience that is one of the best you will have.
