Query: A Cornell student who had to read Guns, Germs, and Steel

I'm a Cornell University freshman and i had to read this book. Guns, Germs, and Steel really ruined my summer. It's very long, repetitive, and not incredibly interesting. I also had to listen to a panel discussion about it and participate in a small group discussion. Every other student I've talked to agrees with my opinion, but hey, you might enjoy it if you like learning about the fates of human societies.
