Reviewers so far seem to have been disappointed. I always await Grisham's with joy, and read them as soon as I get hold of them. This was no exception. I thoroughly enjoyed it, despite the different style. Perhaps I should point out that I enjoy literature for younger people, which perhaps explains why I loved it and others here didn't... But then I wouldn't say it was only for the younger audience anyway. I thought it was nicely written, there seem to be things that haven't really been rounded off, but then, I read somewhere that this might be the start of a series ... which would make rounding everything off pointless. I certainly wouldn't level the same criticisms at it as others reviewing here.
Anyway, a quick read, I enjoyed it immensely, and look forward to the next book (whether or not it's a follow-up to this one!)
**Perhaps I should add, the back cover of the book says something along the lines of 'Grisham for a new generation of readers', which maybe explains the intended-audience shift... **
