Pony Per Book, Fourth Instalment - Update#2

For those who want to have the fourth instalment of Pony Per Book have a little teaser, then read this blog. (It will only contain its title). if not, don't read it.

The next instalment will be called Returning Nightmares. it is a work-in-progress title and I'm not sure whether or not it will be the final title, but it does seem appropriate of what how I'm writing the next instalment.

What do you think the new story will be about?
