Deep Water by Emma Bamford

The dark side of paradise is exposed when a terrified couple reveals their daunting experience on a remote island to their rescuers-only to realize they're still in the grips of the island's secrets-in this intense and startling debut in the tradition of Into the Jungle and The Ruins. When a Navy vessel comes across a yacht in distress in the middle of the vast Indian Ocean, Captain Danial Tengku orders his ship to rush to its aid. On board the yacht is a British couple- a horribly injured man, Jake, and his traumatized wife, Virginie, who breathlessly confesses, It's all my fault. I killed them. Trembling with fear, she reveals their shocking story to Danial. Months earlier, the couple had spent all their savings on a yacht, full of excitement for exploring the high seas and exotic lands together. They start at the busy harbors of Malaysia and, through word of mouth, Jake and Virginie learn about a tiny, isolated island full of unspoiled beaches. When they arrive, they discover they are not the only visitors and quickly become entangled with a motley crew of expat sailors. Soon, Jake and Virginie's adventurous dream turns into a terrifying nightmare. Now, it's up to Danial to determine just how much truth there is in Virginie's alarming tale.
