Once upon a time, New York City had six boroughs, instead of five.
This additional piece of the city was a small island sandwiched between Manhattan's West Side and the New Jersey shore. And one day, the island began to slowly move – drifting away from New York towards the open sea.
This shift transforms the life of the entire city, bringing people together and tearing them apart. As the Mayor and his cronies work to do damage control, two young New Yorkers—Avery (of Manhattan) and Annabelle (of the Sixth Borough)—must learn to face a changing world.
