Marriage is the price, he tells her, and Diandra hesitantly agrees. But after an arduous journey to the breathtaking Lost Valley, she is stunned to discover that local custom demands she be the wife to all of her new husband's virile brothers as well—and that each union must be consummated . . . before the entire village! At first shocked, Diandra soon finds her new role deliciously appealing, as the passionate attentions of three enthusiastic lovers carry her to new pinnacles of erotic satisfaction.

When Yeshi returns to the valley, suddenly Diandra's simple life of nonstop pleasure is not so simple anymore . . . as taboos are broken and passions spin wildly, unexpectedly out of control.
