The Book Thief by Markus Zusak
It takes place in Germany during WWII. It's amazing!
Newes from the dead.
It's not about war, but it's a great thriller.
"Gone With the Wind" by Margaret mitchell qualifies for all of that I think. Plus it's a great book. =)
I don't know any civil war novels off the top of my head but you could read something by Philippa Gregory. She writes historical fiction from the 16th century. She wrote The Other Boleyn girl. You should be able to easily research Mary Boleyn and King Henry VIII.
