'Blue' has some villains who are easily discerned. They're wizards and they live in the north. (don't all the bad guys usually live or come from the north!!!)
I've also got a 'surprise' villain. A person who hides in the shadows, or seems to be a friend, or is kind to animals, and turns out to be the bad guy.I'm hoping I've hidden him/her (won't tell you) well enough. But not too well that it comes as a complete shock when my readers discover who it is. That would not be good!
I hate when you read a book and three pages into it, you know who the bad guy is. I like a little mystery in my coffee.
I hope I've hidden my villain well. My critiquers haven't said they know who it is yet, so there's hope.
Life is a giggle.
