This book is about a boy named Ender brought to a space battle school and learned about battle tactics because of the bugger war, which is an invasion of the bugs from outer space. I chose this book because I was fascinated by the cover of the book, and I like to read about wars, too. The main characters were Ender, Petra, Bean, Colonel Graff, and Alai. Colonel Graff recruits Ender to the battle school. Ender is the commander of Petra, Bean, and Alai. The major problems Ender encounters are jealousy from other people because of his intelligence. My favorite character in the book is colonel Graff because he talks very confidently in all situations, and I like the way he talks. My least favorite part of the story is when Ender comes back to Earth, and starts talking with his sister, which bored me. It would have been better if the buggers attack them while they are talking, and they have to escape to the battle school. I recommend this book to people that like wars because this will be very interesting for them to read.
