This story is a sequel to Don't Look
A sequel to Don't Look but should easily be enjoyed on its own.
Ponieville's primer aviator, (Cherry Berry) after testing her new invitation (an Aircraft named Buttercup) discovers she has a relative she doesn't know and would likely like to meet her. Shenanigans ensue, in the first chapter Derpy's (yes, the old name, but she is what she is and we love her) near death.
Many more chapters to write and look forward to. Intended to be and become a light-hearted adventure story with bits of Aviation, Science, and engineering mixed in for the fun of it. Much inspired by Magic Tree House and Guardians of Ga Hool in this way.
