format for a novel manuscript

Once every hundred years, a silver moon appears in the sky for a single night. On that night, seventeen-year-old Elias Veyron discovers a hidden library buried beneath his village. Inside are six ancient manuscripts, each recording the rise and fall of civilizations that no longer exist. But there should only be six. In the deepest chamber lies a seventh book—unfinished, unwritten, and bearing his name on its cover. When Elias opens it, a sentence appears on the first page: "The Seventh Manuscript begins with the death of its reader." Soon, impossible events start occurring. People vanish from history, memories change overnight, and mysterious figures known as the Librarians of Fate hunt him across the world. To survive, Elias must uncover the truth behind the seven manuscripts, the forgotten authors who created them, and the terrifying secret hidden on the final page: What if the Seventh Manuscript isn't predicting the future... but creating it?
