Wonder Woman #183 (On Sale: May 1, 1969) has another nice cover by Mike Sekowsky and Dick Giordano.
Our feature-length Wonder Woman story "Return to Paradise Island" is written and penciled by Mike Sekowsky and inked by Dick Giordano. Answering her mother, Hippolyta's call for help, Diana and I Ching are brought to Paradise Island only to find Hippolyta lying in an enchanted sleep from which she cannot be awakened. Paradise Island has been terribly ravaged by war, a war brought on by Diana's grandfather, Ares, God of War, in his mad quest to wrest from his daughter, Hippolyta, Queen of the Amazons, the secret of dimensional travel. It is a secret that he needs and want so that he may pour his armies onto Earth and other worlds, knowing that only through war can he again be the powerful god he once was.
Rallying her mother's Amazons to her, Diana leads them against Ares in a desperate attempt to stop him. They fight bravely, but against such overwhelming odds as Ares throws at them, even Amazon bravery and courage cannot prevail. Driven back into the mountains, Diana and her Amazons wait for the battle they must fight and the battle they know they cannot win. It has been reprinted in Wonder Woman #198 and Diana Prince: Wonder Woman Vol. 1 TPB.
