The Things They Carried by Tim O'Brien is one of my favorite books ever. It is a collection of short stories. The longest one (I believe) is the one it starts with "The Things They Carried." I know you're shocked. I'll see if I can find some supplemental material that is online and A/V to help get you in the mood for this collection, but if you are trying to work yourself up to a certain enthusiasm for it, you don't have anything to worry about. You won't regret reading any of these stories. Also, "The Silver Star" features lots of poop, so stay on the look-out for that. (I know you're excited.) If you have a chance, definitely make your way down to DC and walk through the Vietnam War Memorial, if you never have. It will be much more meaningful after you read this book.
Quick fyi: Audible offers audio Cliff's Notes and an audio unabridged version of the short story collection. So if you're a slow reader, you can clean your room and "read" the book.
Mythology edited by Edith Hamilton--it has been a while since I read this and I've read a lot of books on Greek/Roman, Norse, and other mythology. I believe this book focuses on the Greek myths. I love mythology. This isn't my favorite collection; I can't really lie about that. For Greek myths, I know neither of these is strictly high school level, but I love the D'Aulaires Book of Greek Myths and Olivia Coolidge's The Trojan War. Edith Hamilton writes in a very academic style and I feel like a lot of the fun gets lost in her interpretation. Still, she is very thorough. I will revisit my copy and try to give a more thorough review and some notes to help you out soon, so stay tuned.
Audible does offer an unabridged version of Mythology edited by Edith Hamilton.
I am familiar with some of the other items on the Nonfiction and Fiction lists. I'll post an update shortly with an overview on those, and highlight some particularly good resources/pieces.
