About the Ocean Quest series
Ocean Quest is a series of illustrated adventures for readers aged ten to twelve about the ocean, its life and its history. Isla, a free diver, and Marco, a history buff, are the junior crew of a small research submersible flown by an AI captain that answers every question in a riddle. Each book delivers one ocean topic through a real dive with a battery clock, and shows how people found out what lies below.
