Escorting Dr. Maxine O'Neil into the cave known as Devil's Hollow was Zach Douglas's job. Relishing the sparring matches with the type-A scientist was his pleasure. He ran the show in the Texas Hill Country cavern-until sabotage and murder struck the site. Hours spent in the dark, cozied up in tight quarters with Maxine had shown Zach her passionate side. Now he wanted to see the truthful one.What was in that cave that was worth dying for? Only one thing was for sure: whether Maxine liked it or not, Zach would do everything in his power to keep them from being Devil's Hollow's next casualties.
