THE DEVIL'S TUNNELS — Down Where the Maps End
Book three of the CIA Cowboy series takes the fight underground.
Some ground never shows up on a map. The Devil's Tunnels goes there.
This is close work in the dark — no air support, no clean lines, no way out but forward. Sam Martin writes the underground with the claustrophobia of experience rather than imagination.
