Fates or Fables?

From publisher blurb: Fates or Fables is a one-shot adventure balanced for four tier 1 characters, and is written and designed by an African American with heavy influences from their culture. When the party's boat is thrown upon an unknown island, the party encounters a usurped royal family of demi-gods looking to reclaim their throne. Can the party infiltrate the palace of the current ruling family to restore the rightful heirs, or will the whole island suffer the catastrophe of an island disconnected from those who protect it.
