Sea of Gold(Sea of Gold‪)‬

Fish—nicknamed for his skill as a swimmer—never intended to become a pirate.
For starters, he absolutely hates to fight. But while working as a courier, Fish has a mysterious package stolen. To get it back, he joins up with a ship of scalawags on a secret quest for a legendary treasure.
Now swabbing the deck of the Scurvy Mistress, Fish will have to earn the trust of the fortune-obsessed pirate captain and learn the ropes from the rest of the crew, including Daniel, a boy encyclopedia on all things piracy; Nate, a tough-as-nails young thief; and Nora, a
fearless girl with knives up her sleeves. Yet with mutiny on the horizon and a ruthless first mate testing him at every turn, Fish isn’t sure he’ll survive, let alone discover the secret of the stolen package.
Armed only with wit, courage, and determination, Fish leads his new friends in the fight of their young lives and a hunt for hidden gold.
