Months have passed since Flash's return, and everything is great in Equestria. Lightning is happily living his life and trying to decide if it's time to take his and Rarity's relationship to the next level.

But before he can, a new threat has appeared. A threat that seems to wield a magic like no other, one that no pony will see coming. With this new enemy demanding the end of Twilight's new reign, Lightning and his friends soon find they are the only thing that can stop them. But when a sacrifice is needed to overcome this threat, Lightning finds himself with an impossible choice: Save Equestria, or save those closest to him.
