The first of three books.
A mysterious letter shows up in Princess Celestia's office, and when it nearly causes her death, it's up to the Mane 6 to take her place as ruler of Equestria.

My first proper fic on this site. Any criticism is appreciated, but please, not too rough.

Rated teen because it can be suggestive, but this may be bumped up.

Feel free to comment, but please, no spoilers.

Cover art is needed... PM me for more information.
