The Writer and The Princesses

Jacob David, aka Ink Heart is a writer. A rather prolific one at that. His life is complicated enough what with suffering from schizophrenia, having an editor who won't get off his tail, and finding himself occasionally appearing in Equestria turning into a pony. He finds himself becoming fast friends with Twilight Sparkle under his Alias of Ink Heart, enough so that he reveals everything to her and yet, no one believes him that he is Ink Heart except Twilight who they believe he has bespelled. What is a writer to do when life forces him to meet Princesses?
