Under Pressure. An Underwater Investigation, #4

Underwater investigator Hannah Sampson is gearing up to dive on a flawless tropical morning, marred only by the reports of a distant storm brewing in the Atlantic, when the sea turns to carnage-an airplane plunges into the water just yards off the bow of her boat. Minutes later, Hannah and her dive partner are sixty feet below the surface, vying with sharks to pull victims out of the wreckage. One of those victims is a nine year old boy who will change Hannah forever.
