The question in itself is simple, but the answer isn't so. And after discovering a hidden page in her dad's journal, Sunny finds a clue that begins a long train of investigating that takes her and her friends across Equestria and beyond, to find out what happened all those years ago, to finally find the answers Sunny's been wanting about the Fall of Equestria.
