Meet ocean explorer Sandy Fin, silver-scaled diver of the deep, puzzler of puzzles and daring hero of a hilarious middle grade series by Martin Stewart, illustrated in black and white.

Sandy Fin and his best friend Lily are enjoying life by the sea, after saving Portwhistle and its marine life from Albo Start’s aquapark.

Suddenly, odd things start to occur: an escaped convict is on the loose, curious mounds of sand appear on the beach. Strangest of all are reported sightings of the Phantom Diver – a figure of Portwhistle legend, long believed to be a figment of the most inventive imagination!

Suspicious, Sandy and Lily dive, snoop and climb their way through the mystery towards the Phantom Diver’s true identity.
