The Crystal Warriors

Summoned through a sorcerer's portal to faraway Haven, U.S. Captain Mark Phillips and Captain Ikawa Yoshio of the Japanese Imperial Army face powers far beyond what they knew in World War II. Sworn enemies, they must unite to survive. Their latent magical talents are discovered as they trade their primitive rifles and grenades for the crystals that focus their awesome killing energies. And the war is on, a war with vast rewards for the victors.
