Tarzan. The Return of Tarzan #2 (1997)

There are stories of a great, ancient city within the jungles of Africa, a place which, legend has it, served as an outpost to the citizens of Atlantis. This is the fabulous city of Opar. But some legends are best left as dreams, as Tarzan discovers when he locates the city and is chosen to be a sacrifice to the sun god the citizens worship!
