A few years back there was a publishing sensation in the Fantasy/SF world: A fantasy novel written by a fifteen year old kid! Awesome!
I read the cover blurb at the bookstore and reckoned I could save myself a few bucks. "Oh, look! Another hackneyed Tolkien ripoff D&D romp! Yawn."
Thanks to the Critical Bookworm, I feel smugly certain that I was righter than I knew.
(...and a totally unrelated PS to budding fantasy authors:
I know making up your own language makes you feel cool and all, can let you pad out your novel with appendices, dictionaries, & alphabet charts, and gives you reason to use the word "verisimilitude" in polite company, but harken to my warning: The Kindly Professor made up a language because he was a professor of linguistics, and then made up some stories to give it a home. Trying to make up a language to fit in your story when the last English course you took was Grammar/Comp 122 is unlikely to be anywhere near as successful...)
