Definitely 10 pens.
This book may just be the best, awesomest, coolest sci-fi book I’ve ever read.
It’s about a 6- year old genius who is selected to go to battle school, a place where boys and girls train to fight the buggers, who are trying to take out the overpopulated human race. Ender finds himself winning every battle with his team.
Ender must face challenges, such as bullies, while dealing with the stress of the fate of the human race on his shoulders and his shoulders alone.
I can’t tell you any more, because this book has an ending so great you’ll be staying up until you can’t hold your eyelids open any more.
Sorry I haven’t reviewed in a while! More coming though!
