I received some comments about my YA book, Invasion From Fred, saying that the vocabulary in it was too advanced for younger readers. I put a lot of serious though to this issue when I wrote the book. Two things made me decide to challenge my young readers. The first is a social issue. I feel we are doing too much “dumbing down” of material that’s presented to the American public. (And it’s not happenstance that I’m saying this during an election year.) I didn’t want to give my young readers something that was easy to read. I wanted to challenge them. The second factor that motivated me to use a larger vocabulary, was the fact that I knew most of my sales would be in the e-book format. If you see a word you don’t understand in an e-book, you can just highlight it, and the device will give you the dictionary definition of the word. I decided to give my young readers the opportunity to improve their vocabulary.
