Book Description: At last -- the untold chapter in the history of Star Trek's most notorious villain, KHAN. Searing and powerful, To Reign in Hell 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.
Haunted by the memory of Khan's murderous campaign of vengeance, James T. Kirk now revisits the forbidding world of Ceti Alpha V to discover for himself what ultimately drove Khan to madness. There, buried beneath the desolate surface of a dying planet, Kirk and his allies find the untold story of their greatest foe -- and of the woman who loved him: Lieutenant Marla McGivers of Starfleet.
Along with Khan's genetically engineered followers from the twentieth century, Khan and Marla are left on Ceti Alpha V with the hopes of building a new life together. Although the planet is savage and untamed, Khan dreams of carving out an empire even greater than the one he once ruled on Earth. But when global catastrophe strikes, 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.
