Fin Fleming is an accomplished scuba diver and chief underwater photographer at a famed oceanography institute on Grand Cayman. Her best friends disappear, and it doesn’t take long for the kidnapper to contact her with demands.

Since the kidnapping occurred on the water, the police have asked for her help. She’d do anything to save her friends, so she dives right in to solve the mystery. But it’s not easy. There’s a killer shark in the area and someone is stealing scuba tanks from her dive shop.

With all that going on, will she find Gus and Theresa before it’s too late?

Listen to Dark Tide to find out.
