F TARZAN
As the rich Lord Greystoke, Tarzan found himself the target of greedy, evil men. Stranded on a desert island, his wife and son kidnapped, Tarzan's plight seemed helpless. But with the help of Sheeta, the ferocious panther, and the great ape Akut, Tarzan crafted his escape with the giant Mugambi. Yet the trail of the kidnappers led deep into the interior--and it would take all of Tarzan's skills to reach his family in time.

THE SON OF TARZAN
Tarzan's young son narrowly escaped the wrath of his father's nemesis Paulvitch, and he was forced to flee into the savage African jungles where Tarzan himself had been reared. There the civilized boy would have to learn to face the great beasts and exotic dangers only his father had ever conquered. And as he became known as Korak the Killer--whose legend would rival that of Tarzan--he would learn that the dangers of the jungle were nothing compared to those devised by men . . .
