Meet ocean explorer Sandy Fin, silver-scaled diver of the deep, puzzler of puzzles and hero of a new madcap middlegrade series from Martin Stewart, illustrated by Pedro Rodríguez.

Sandy Fin lives in the Museum of Seaside Stories with the famous explorer Emile du Pont and their collection of treasures. Sandy and his best friend Lily are being taught the art of diving, aided by Emile’s ingenious inventions.

When the museum's future is in peril, it is up to Sandy and Lily to find a precious relic - the fabled Brass Monkey - which legend states will bring prosperity back to the town. But then Albo Start arrives! Start plans to turn Portwhistle Bay into a Seaworld-style theme park named Splash Landing, locking up Portwhistle’s cherished marine life in tiny tanks.

Sensing skulduggery, Sandy and Lily set out to stop Start, armed with banana sandwiches, moonlit sneezes and noses for danger.
