I just recently started to write stories directly towards the FiM actively, though I have been writing for years, publishing numerous stories at Mibba and the eventual pony story, as far as to the MLP
We had realised, we can't give Spike any material posessions, but we could borrow them to him for limited periods of time for him to enjoy them. This is what a Library is for.
Books, I love them all. Although I guess I was initially shocked as Spike found this one, for me. The book does remind me of my time at the Canterlot High. I never had expected to see a book like this. Not in my old library.
