This book is awesome
I just got done reading it

Well it's about this genuis book that gets drafted to a futuristic military school.
Kinda.

Does anybody know if this book is part of a series?

Amazing book. My favorite actually. There are others;

"Ender's Shadow" (About Bean)
"Shadow of the Hegemon"
"Shadow Games"
"Xenocide"

That's all I remember. Great books, Orson Scott Card is amazing.

I know
I'm usually not one for reading but this one I couldn't stop.

Are those in order?

There really is no order except you have to read "Ender's Game" first. Then you can read the rest in any order you wish
