The first shout out goes to @PippinKK.

Though I might be a little biased due to the fact that KK is my kid sister, her stories really are very good. She writes with great grammar and spelling, and though many of her stories ARE fanfictions, they are still very well written and worth reading.

Of special note is her original story "Not Alone". Intriguing from the get-go, this story is detailed and she had worked quite hard on it.

Though she does not update as regularly as I would like, her updates are usually worth waiting for.

Also, if you are looking for a good 'Ask the CreepyPasta's' book, she has recently restarted hers. She is quite decent at staying in-character, and tries her hardest to update regularly.

Again, her username is @PippinKK.
