My feeling, which I gather is pretty similar to the view of a lot of people, is that Ender's Game
is the best of the bunch, the trilogy that follows is reasonably good but essentially very different, and the whole Bean series... well, I think I gave up on it after the first book, which I found pretty implausible and not engaging enough to be worth it. It was trying to tell a parallel story to Ender's Game
, but that just threw its own inadequacies in comparison to EG into sharp relief. It was pretty well-named -- a mere shadow of the original.
