Having discovered the message left for her by Star Swirl the Bearded in the distant past, Twilight once again finds herself caught up in the middle of a struggle against forces far greater than herself. In order to even stand a chance she'll need to travel further and wider than she ever has, and forge some unlikely alliances with old enemies. All to bring down the powers that have manipulated and shaped her entire life, and retake control of her own future.

Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.

This story is a sequel to You Can Fight Fate

Time loops? The end of existence as we know it? Fate itself conspiring against you? Who has the energy to deal with that kind of thing?

Not Cloud Kicker, that's for sure. She's a mare who knows what she wants out of life. An easy job, a nice house, and an endless supply of potential banging partners. Then one day a simple little flower vendor moves in down the street and everything starts to change.

As a side story to the main Time Loop Trilogy, you can expect massive spoilers in the comments for both the original stories and unwritten chapters of this one.
