The Secret of Raven's Tooth

By Darryl Martel.
When siblings Jack (11) and Rosie (9) visit their adventurous cousin Finn (10) for the summer in a remote coastal town, they expect lazy days by the sea. Instead, they stumble upon a mystery, a lost map hinting at a hidden island that doesn't appear on any modern charts. With their new friend Ava (10), a local girl with a talent for sailing, they set out on an adventure that tests their courage, resourcefulness, and friendship.

But the island holds secrets beyond their wildest imagination. Strange markings, abandoned structures, and a hidden danger lurking beneath the surface turn their summer into the adventure of a lifetime.
