Shadows Over the Tenebrous Sea (Paperback) (ISBN-13: 9798294745646)

Isla and Benjamin dream of adventure beyond their quiet village of Covehaven. When Isla discovers a hidden map leading to the legendary treasure of Blackrock Isle, they set sail, determined to claim it-despite warnings of cursed waters and lurking dangers.

Their quest takes a wild turn when they meet Aquillo, a merwizard searching for a lost harp that can free his people. Teaming up, they battle treacherous storms, outwit ruthless treasure hunters, and uncover eerie island secrets. With the help of Peter, a ghost bound to the treasure he once sought, they navigate a deadly cave-only to face a monstrous guardian determined to keep the treasure hidden forever.

To survive, they must rely on courage, cleverness, and each other. But will the treasure be worth the risk-or will Blackrock Isle claim them, too?
