Thinking about my Next Book

I would like to do something different for my next book. What do you think about my writing a fantasy?  Light fantasy—maybe a weather witch and an enchantress, hedge witches and hags and the daughter of a wise woman. No vampires, no wizards, no walking dead. I am playing around with the idea but I hit a brick wall when I come to the fantasy stuff. Who knew I was so practical and literal? And I seem to be creating an evil force that can’t be defeated. Hmmm. Maybe I should try a romance novel or a picture book instead.
