When treasure hunter Jack Harvey and his partner Emma Morgan recover a mysterious gemstone from a sunken yacht, they believe they’ve stumbled upon a simple salvage operation. But the Heart Stone is far more than a beautiful artifact—it’s the key to unlocking one of history’s greatest mysteries: the lost Crown Jewels of King John, missing since 1216.

Guided by the cryptic diary of Elias Stewart, a obsessed treasure hunter from the 1920s, Jack and Emma find themselves thrust into a deadly race against the Coalition, a ruthless organization that has pursued these legendary stones for eight centuries. With the help of CIA operative Jensen Hunter and historian Dr. Marin Hart, they must locate four additional gemstones scattered across the globe—from the volcanic depths of Mount Teide to the treacherous waters of Croatia’s Blue Cave, from the rainforests of Bosnia to the windswept shores of Scotland.

But the stones are only part of the puzzle. An ancient alchemist named Alara designed an ingenious system to protect the treasure from those who would use it for evil. Only the worthy can decipher her clues, survive her trials, and unlock the secret of Crystal Haven.

As Jack and Emma close in on their goal, they discover they’re not just fighting the Coalition—they’re caught between the mysterious Cabal Consilium, who claim to be guardians of ancient secrets, and forces,  who have agendas of their own when it comes to the treasure. When Emma is kidnapped and used as leverage, the stakes become personal. The team must risk everything to recover the final piece of the puzzle: a golden halo that will reveal where the Crown Jewels have been hidden for over 800 years.

From the depths of the Atlantic to the crypts beneath Canterbury’s oldest church, Crystal Haven is a pulse-pounding thriller that combines historical mystery, cutting-edge adventure, and the timeless appeal of a treasure hunt. With betrayals at every turn, ancient puzzles to solve, and enemies who will kill to possess the stones, Jack and Emma must prove themselves worthy of Alara’s legacy—or die trying.

Perfect for fans of Clive Cussler, James Rollins, and the National Treasure films, Crystal Haven: Legend of the Lost Stones delivers non-stop action, ingenious historical puzzles, and a treasure worth dying for.
