Novella, such a fancy word, huh? But, what is it exactly? Well, according to Wikipedia, a novella is a work of narrative fiction that is longer than a short story but shorter than a novel, being its word count somewhere between 15,000 and 40,000 words.
In our case, as our stories are not going to be as short as a sneeze nor as long as a walk to the top of Mount Everest, we fall under this category. But well, call them as you like. Longer or shorter they are still stories, right?
