Tunnel Rat — John Ward

When former US Army captain Eric Tucker decided to visit Old City in Jerusalem with his daughter and granddaughter, he thought it would be a chance to get some family time with his girls and enjoy his retirement. But when a terrorist organization threatens his family's safety, Captain Tucker must reach into his past in order to survive. Can he do so without becoming the cold-blooded killer he once was?

Emir Farouk is falling on hard times, and the loyalty that once came so easily to him is dwindling. When an old man and a teenage girl from America appear in his sights, he believes it is a sign and orders his men to kidnap them. But things don't go as planned…

What follows is an intense cat-and-mouse game between a powerful terrorist cell and one man who's determined to protect his family, the woman he loves, and his ship. Captain Tucker can't -- and won't -- give in, even if it means returning to the man who led an elite unit of soldiers into claustrophobic tunnels after their enemies with nothing but flashlights, knives, and pistols: the infamous Tunnel Rats.
