A Lucky Day to Die (Stone Soldiers #10) - Stone Soldiers, #10

A witch has come to Las Vegas, Nevada, taking over a casino and luring gamblers to a fate worse than death. Supersoldier Mark Kenslir heads West to find out just what is going on in the one safe-place designated for America's supernatural citizens--a place the Stone Soldiers are not authorized to deploy. Operating off the books with his granddaughter, pregnant wife and Vampire M. D. in tow, Kenslir must brave a Hellish tower of decadence and prove that the Strip needs its Amnesty revoked.
The Stone Soldiers are America's secret weapon against the forces of darkness. A small detachment of psychics, supernatural soldiers and men turned to living stone, they respond to threats conventional forces are not prepared to face. Battling myths, monsters and magic around the world, the men and women of Detachment 1039 stand ready to do whatever it takes to stop evil in its tracks.
