The GridCompact Disc, 25 August 2015

A former federal law enforcement contractor with a somewhat spotty record, Jon Cantrell has seen--and done--just about everything. Now he's a sheriff, keeping the peace in small-town Texas. He thought that he'd finally settled into a quiet, less-complicated life--until his deputy gets himself murdered. Soon Cantrell's search for the killer points to an online-dating site designed for extramarital affairs and to a woman who may have been the unfortunate deputy's last date.

Meanwhile, someone is staging a series of seemingly random attacks on the regional power grid, and Cantrell is reluctantly pulled back into the federal fray when he accepts an off-the-books assignment to uncover the culprit. With the power company and the feds impatient for an arrest--and clues in his deputy's case pointing to something more sinister--Cantrell must run parallel, conflicting investigations. But will he find what he's looking for? Or is he about to take a fall?
