This story is a sequel to Alicorn training... with Applejack?
Books rarely fail Twilight. Friendship is the only thing she couldn't master just by reading a good book, after all; everything else is there, in the library, she just needs to know where to look.
But now her newfound earth pony powers prove to be a mystery. Why are there almost no books about them? And why are the few ones that exist locked in a forbidden section of Canterlot Library? The newly-ascended alicorn decides to investigate it herself, but what she finds only makes her ask more questions.
Sequel written thanks to my fans. If you want to see more stories from me, consider supporting me in some way!
