Prologue: The Nightmare Prince

Jackson Overland Pitchiner, popularly called Jack Frost, is the son of The Nightmare King.
He was born on the Isle of the Lost. Unlike most teens on the Isle, he's a loner. He may socialize and occasionally join in some fun, but he's not a gang joiner. He stayed out of Mal's gang's way and the same with Uma's. He usually sticks to his legend of being there but not a part of anything.
But he was also friends with Carlos...maybe even best friends-till Carlos started hanging out with Mal, Jay, and Evie.
After they left for Auradon Prep, Jack had zero contact with Carlos; until a letter arrives inviting him to Auradon Prep by recommendation of Carlos! How will Jack Frost adjust?
