Ender's game was really good.

The books that follow are alright

This is my favorite book by far. The entire series is great!

Ender's game was great. I thought Speaker for the Dead was better though ^^. The books that followed really did it for me.

Speaker wasn't bad. Probably OSC's only other good book. But it was nowhere near as powerful or gripping as Ender's Game. One of the truly great reads in the last 20+ years of Sci-fi. Its the book I give out to everyone whose just starting out in the genre.

I'd recommend it to any book lover, it's that good. I'm not an avid sci-fi reader, and I still find myself reading Ender's Game from time to time.

Ender's game itself is definitely a great book, but past that it gets deeper, and at times confusing. It goes from a book about entertainment to discussing stuff like moral values and such.
