Black Reef (en Inglés) - Glen Hatcher

A man is dead. A treasure hunter is missing. And beneath a beautiful Bahamian reef, someone has been keeping secrets for eight years.

When a tourist is killed by a shark near the isolated Cinder Cay, local dive operator Zadie Albury refuses to accept the easy explanations already being written around his death. The sharks are real, but so are the questions surrounding a film crew, unexplained activity on the reef, and an expedition determined to reach a site hidden beneath the island.

Then treasure hunter Quentin Cazalet disappears inside the underwater cave system.

The search leads Zadie, marine biologist Tamsyn Orrell, former naval diver Gethin Hesketh and the film crew into a breathtaking labyrinth of flooded caverns, forgotten passages and hidden chambers. What begins as a rescue becomes something far more dangerous when they discover evidence of an earlier expedition, a lost cache of historical treasure, and a death that may never have happened the way everyone was told.

Outside the cave, sharks continue to move through the reef.

Inside, the route home is closing.

And as old lies begin to surface, the survivors must decide who they can trust before Cinder Cay takes another life.

Black Reef is a tense, atmospheric underwater thriller about survival, buried history, dangerous ambition and the stories people tell themselves when the truth becomes inconvenient.
