Flash And Fathom

She came to uncover a conspiracy, and he brought her underground to use as his greatest weapon.

Relentless investigative journalist Tova Renn is chasing the story of a lifetime concerning an eight year old environmental cover up poisoning Florida's aquifer. Her pursuit leads her to the Swallowtail Spring expedition and right into the hands of Cassian Voss, a cold cave cartographer and local dive legend. Cassian knows every flooded passage of the subterranean labyrinth, and he knows exactly who murdered his brother down there. When a violent flash flood collapses the cave entrance, Tova and Cassian are sealed hundreds of feet underground in pitch black darkness. As they navigate submerged passages sharing limited air, Tova realizes her presence in the dark isn't an accident, but the final piece of Cassian's obsessive puzzle. Now she must decide if she can trust the hands guiding her through the abyss, especially when the man keeping her alive might be the most dangerous thing in the cave.
