Zoe is not one of the "in" crowd. Somewhat shy and bookish, she has always kept to herself. When her father buys a lakeside cottage and brings her along for a summer vacation she finds it a perfect retreat. But there she meets and is adopted by a brash, outgoing girl who quickly adopts her into a group of very strange, hedonistic young people more into drugs, liquor and sex than poetry or academics. Zoe finds all her inhibitions and fears must be pushed aside if she wants to prevent herself from being cast out. The group pressures her to submit, and she does, giving in to demands for sex, for obedience to the group's will, for more and more outrageous and sexually provocative behavior. She becomes their servant, their gopher, and, in effect, their sex slave. Finding her submission deliciously erotic, they push her further, reveling in their control over her as much as she revels in the hot, steamy sexually charged game. She is punished, strapped, and humiliated, but glories in the dark heat and erotic life, in doing wild, slutty, kinky things she had only ever dreamed of before. She could have spent the summer reading books and writing poetry, and instead, is spending it as a naked sex slave, experiencing one shocking thing after another. But how far will their game go?
