Join ocean explorer Sandy Fin and his best friend Lily in the third adventure in the hilarious middle grade series by Martin Stewart, illustrated in black and white.

Portwhistle is under threat from a pirate curse! Sandy and his best friend, Lily, must set sail in search of Blackbeard’s silver-plated skull to save their home. The skull is rumoured to be on a shipwreck far out to sea.

It is a perilous and puzzle-filled quest and Sandy and Lily must face three dangerous guardians lying in wait, not to mention Tye and his pirate-obsessed pals, the Buccanhiers, tagging along.

It’s a race to get to the sunken pirate ship first… if at all…
