"I followed the next couple of books in the series, but couldn't get into them to the same extent."
Ender's Game is a bizarre series. The first book is a juvenile. An adult may enjoy it, but it's a light snack. Everything else in the series is high-concept hard-core science fiction. As hard-core sci-fi goes, by modern standards its probably a bit lightweight, but it certainly doesn't fit into any other genre. (Well, I guess I haven't read the really recent stuff, so I don't know about those.)
I am actually grateful it took me years to learn there were sequels. I only found them once I could mostly understand them, and a re-read several years later still showed me stuff I missed the first time around.
