A very exciting author reply came yesterday: Jasper Fforde! (See my original email here.) He was the first author I wrote to! He is definitely one of my favorite authors of all time. In my email to him I mentioned how one of his books (Shades of Grey) reminded me of The Giver by Lois Lowry. He said that many have pointed out the connection to The Giver, and that there is another book (he didn't say what) that people said was similar. He also said that he's glad that in the entire genre of fantasy, only two books have been mentioned to have similar themes.
I think that it's very cool that he wrote back! I wasn't really expecting him to. On his site he says not to expect it. I have another author reply for tomorrow, so expect that and another review!
