Author Greg Cox masterfully bridges the time period between Khan Noonien Singh's twenty-third-century revival in the Original Series classic episode "Space Seed" and his unforgettable return in the acclaimed feature film Star Trek II: The Wrath of Khan.

When global catastrophe strikes his new planet, Ceti Alpha V, Khan must use every ounce of his superhuman strength and intellect to wage a fearsome battle against the planet, his people and the growing darkness in his own soul.
