Sunny Starscout's house is in ruins after the incident with Sprout. Now she's staying temporarily with Pipp and Zipp in Zypher Heights. There, she meets someone she never knew she needed. A mom named Sky Liner, and a sister named Moon Mist.

Now, she has to figure out how she fits in with her new family dynamic and what it is like to build trust from the ground up with ponies that should have been there from the beginning. She also has to realize, sometimes friends simply won't always like your family.
