Octavia has received an invitation to attend the Magna Anima Nocte, a celebration of the Night through music—a tradition lost for a thousand years, now born again after the defeat of Nightmare Moon and the return of Princess Luna.

But there, under the light of the stars, darkness churns and awaits, and while the rewards seem promising, maybe there is something to the words a certain gypsy told her. Octavia will have to match wits with other competitors, fight for her right to win and unravel the enigma of Winter Charm, the mysterious patron behind the event.

Luna discovers something hidden from Celestia for twenty years, now, with emotions running high, she enlists the help of the Mane 6... but what seemed to be a single mystery, soon reveals a darker and much more complicated plot that will soon decide the fate of Equestria.
