I used to love doing book reports because it gave me an excuse to read fiction "but ma, I'm doing homework!"
I haven't read neither of the books you've mentioned so can't help there. If it's interesting, give it a shot. And remember, you don't have to like a book (or even read a good book) to write a good report. Choose an angle and write. Character studies are always fun.
P/S:Short stories are awesome too.
