So a while back, I read a review for a YA book that is going to be released next spring and I had to do a facepalm. The name of the government in my book (that I thought was original, btw) is the name of the government in the other book. A book that is going to be published. Ugh! Then a few days ago, I read a review of another YA book that is going to be released soon and I discovered that something else I used in my book has been used in this other book. And it's something I will definitely have to change. *double facepalm*
Have you ever written a book and discovered that some of your ideas have already been used?
