Return to the Deep...If You Dare! Years ago, the Aquatica Project used genetically altered sharks in hopes to develop a cutting-edge cure for Alzheimer’s disease. They came close to achieving their goal, but an unforeseen tragedy derailed the experiment. Now, pharmaceutical billionaire Carl Monroe is determined to revive the research of the undersea laboratory. With former Navy SEAL Trent Slater and scientists Daniel and Leslie Kim already on board, Monroe hopes to enlist shark conservationist Misty Calhoun to the team. But Calhoun is shocked to learn that the company is using unpredictable and highly aggressive bull sharks as its test subjects, the most lethal predator in the sea. Before long, the drug-enhanced sharks, led by den mother Bella, are growing smarter, quicker, and much, much deadlier. Brace yourself for unyielding suspense in this bloodthirsty return to the deep blue sea!
