There are a lot of good guy books here. Toni Morrison is a Nobel Prize winner. I read her novel, The Bluest Eye, and was very impressed. I want to read a lot more of her books, but they're certainly not just for guys.
Silvey recommends fiction, nonfiction, poetry, and graphic novels. I like getting ideas about what to read from other readers, and I highly recommend 500 Great Books for Teens.
