Sensation Comics Featuring Wonder Woman #17

"Diana's compassion is tested when Dr. Barbara Minerva appears, begging for assistance as she seeks out the last remaining source of urzkatarga, the plant that supplies the serum that transforms her into the Cheetah. And if she can't use it to replenish her supply, she'll die. But when the Amazon princess/super-hero and the scientist/super-villain make their way to the 'Island of Lost Souls,' they find more is at stake than expected!"
