Is he, really? He enjoys reading but isn't considered gifted or anything. 5B for English in his year 6 SATS
He brought the book home from school because it's worth lots of points in Accelerated Reading (if he can answer the questions!) He appears to have read the first 100 or so pages and can tell me a basic plotline, although I've never read it so have no idea if he's right.
Is it possible that it can be read on two levels, a simple plot and a deeper meaning and that he's enjoying the basic story, rather than the whole book IYSWIM? Or is he just reading words on a page?
