It's been very interesting to read everyone's opinions on the Ender series, particularly the disparity in tone and style between some of the volumes. I've just this week finished 'Children of the Mind' and am still a little undecided about whether or not I really enjoyed it. While it's by no means a bad book, it left me feeling a little flat. Perhaps it was the lack of Ender himself and the rather cursory (almost offhand) way in which he "died". Call me sentimental, but I think the old boy deserved a bigger send off.
The real trouble with "Children of the Mind' though, was that it definitely felt like an appendix to 'Xenocide', which was a book I really struggled with. It tackled some hugley interesting and very deep subject matter but, after the toned and trim pace of the first two books, it felt terribly flabby and introspective.
Maybe it was just the change in tone that threw me. Either way, I'm looking forward to moving on to the Shadow saga.
