Wallflower Blush and Sunset Shimmer have been dating for a little while, and things seem to be going okay. However, when Sunset accidentally reads Wallflower's mind, she discovers that her girlfriend may not be doing as well as she thought.
After a week without any response from Sunset, Sunshine finally receives a message from the girl that could be her first daughter. But before she can accept, she will need to discover something she missed most of her life.

The many facets which once checked a now-dead ancient evil are now gone, and a shred of that evil has returned. And now its former prison threatens to steal all magic from everywhere. The complications grow from there.
