orson scott card: the ender saga

[matt]

almost finished xenocide which is the the third book and have to say the series so far has been of the rather excellent, intelligent, philosophical science fiction variety

definitely recommended, your starting poiint is the first book in the series ender's game which is a wonderful, page turning read and you don't need to read any more books in the series after that as the first book is kind of self-contained

if you do however read more, you'll certainly be rewarded
