Britain's librarians have posted a list of books to read before you die right here.
I think I went to a really good high school (go, public education!), because I have read 23 out of 30, many of them in high school. I hadn't heard of Birdsong or The Master and Margarita before. A few of these I just haven't gotten to. And I just have to say, "The Lovely Bones????? Are you kidding me?" Man, I hated that book. Actually, I liked it until the convoluted, tacked-on ending, which ruined that book for me. Ugh.
