The bad news; There is no key to happiness.
The good news; It isn't locked.

Life is a delicate thing, only happening once and all. For Twilight, the one life she's able to unequivocally call her own has been recently turned on its head. It's not every day you inherit the duties of a kingdom, and to add onto that, become an alicorn. On the zenith of a new life, the young princess is taking time to prepare both herself and her assistant for what to come. Fortunately for her, good times and laughter never disappear at the library...No matter how strange the future may look.
