Hello! I am the late Twilight Sparkle. The book that you will coninue on to read is my knowledge summarised into as little a package as I could possibly manage!
I hope you, dear reader, find this to your liking and that it advances your knowledge of the magical field. Who knows? Maybe I’ve inspired the next me!

Twilight likes books. Twilight knows that not everyone does, but Twilight knows that everyone loves some level of knowledge. So, the obvious conclusion is a short guide to her favourite subject, yes?

Spoiler, Twilight is dead, giving up her alicorn immortality as Pinkie Pie, the final Element of Harmony, died. Her will includes three books of compiled knowledge meant for the reading of your average Equestrian, and not for prodigies like her; the first has been released, and it is magic.
