Enders Game
I've read another book on Rory's list. It was Enders Game by Orson Scott Card.
I enjoyed it but it wouldn't be on my list of all time great books. It struck me how long it was since I'd read a science-fiction novel. It reminded me of Robert Heinlein's work.
It's about a super-bright young kid that is shipped off to battle school to learn to be a commander. The world at that stage is trying to breed a super-commander for an upcoming confrontation with the “Buggers”. I have to laugh when I saw the name. My youngest daughter was often called “Bugger” as her cousin couldn't say Margaret and it came out as Bugger and the name just stuck :-)
