Special and not one of the popular crowd, the letter K can be hard or soft, assertive or silent. A challenging letter to be used to start a title, it can knot up emotions, fly a kite with surprise, and kill with kindness. Subject to identity crises with C and N, this letter is challenging. Even knowing that, there are few stories which fit this category.
Think of kittens killing small knots of fuzzy string. If that does not make you smile, you need to work on your karma!
