By the time the ship reached Mars, jealous rivalry over the love of Gail Loring had turned the Jehad into a crucible of tension and strife. But their internal struggles were nothing compared to the threat of the grotesque Martians who used electrical energy as a weapon of war. Suddenly, the Earthmen had to unite to stave off a massed Martian attack--a fight which, if lost, meant isolation and death on Mars and, if won, meant bucking Spartan's demonic schemes.
