Blood Heat Zero — Don Pendleton

FROZEN HELL
Mack Bolan, exhausted by the firestorm that is his life, decides to take a well-deserved R and R. But instead of some tropical resort, the Executioner plans to challenge nature's whims in the depths of an Icelandic glacier.

On a perilous trip beneath the polar ice cap, he makes a discovery so startling it is tantamount to an act of war.

And the innocent vacation becomes a hunt -- with Bolan as the prey.
