I'm a high school English teacher looking for 2-1 or 3-1 deals on Pulitzer prize winning novels and/or National Book Award winners.  So if anyone has two more of the following books (or others you know of that aren't on this list), please PM me so we can work something out.  Thanks!

Books I'm looking for in any sort of combination:

"The Shipping News" by Annie Proulx
"Gilead," by Marilynne Robinson
"American Gods," by Neil Gaiman
"American Pastoral" by Philip Roth
"The Amazing Adventures of Kavalier & Clay"
"The Echo Maker" by Richard Powers
"The Thirteenth Tale" by Diane Sutterfield

I'm also open to any other books that have won awards for one reason or another.  Please let me know if anyone can help me out!  Thank you so much!
