Twilight Sparkle marries a book and has a family. Then they die in a freak accident, leading her to go on a quest for revenge.
Then we do it again in more detail, because honestly the writer is not in control here. The story goes wither it wills.

Both chapters are telling kind of the same story, but authorial intent is that you read both in order. Trust me on this. I am the author.

This started as a response I made to an offhand joke about Twilight marrying a book, which took the form of a brief description of an increasingly implausible series of events that followed. I later decided to turn it into a proper story, but it came out as kind of a sequel to the original response (at least, that's my opinion). So I had to clean up my comment into a more readable story (while being careful not to change it significantly this time) and include it as the first chapter.
