I would definitely recommend this book - and the whole series along with it, including the Ender’s Shadow Saga.
Need to dig out and re-read the Worthing Saga sometime - many years since I read it.
Oddly enough re-reading Ender’s Game more recently I was in some vague way disappointed. I definitely think there are parts of Orson Scott Card’s writing which have tightened up over the years, but on the other hand I know I’m predisposed to series’’’’ of book rather than onesers due to the amount of travel time I get.
Ender’s Game is one of a number of stories which has appeared in various forms and thus its quite a nice one to use to explore the extension from a short story to 200 page novel, if you are into that sort of thing (I’m not so much, but I have other family members who are, and I do understand that it could be of interest).
Anyway… that’s all, otherwise people will get worried about me escaping from the gutter.
