When Princess Celestia comes down with a mysterious illness despite her immortality, her loved ones flock to her side, including Sunset Shimmer. With only so much time left, Sunset takes it upon herself and Twilight to get to the bottom of it. The two of them work together non-stop to find a cure, which would be fine, if Sunset had gotten around to telling any of them she's dating the other world's Twilight.

It all started with a simple question. "Can the portal go to other places besides Equestria?

The answer turned out to be "No, but we might be able to make one that can."

When their research is complete, Sunset and Twilight are pulled into an adventure in another world, where they meet even more doppelgängers of themselves. But their alternate counterparts may reveal some things about themselves they never knew.

This story is a sequel to Long Road to Friendship

It is a new year for Sunset Shimmer; a fresh chance at real happiness with her five best friends and her girlfriend. But Sunset is constantly troubled by her uncertain future, and haunted by the consequences of her past.

For her battle against Princess Twilight has drawn forth ancient forces with eyes on the last bastion of magic: Canterlot City.

As darkness closes in, Sunset must find her light and guide her friends to defend their world against old rivals and legends best left forgotten, all while dealing with their ever-looming futures.

But when graduation comes, what will Sunset Shimmer do? For she is still a stranger in this world, with or without her friends, and the road before her guarantees nothing.

Of course, with the universe conspiring against her, it'll be a miracle if she even makes it that far...
