From the Introduction, by editor Laura Furman:

Shannon Cain's “The Necessity of Certain Behaviors” begins with the words “To escape,” and for much of the story it seems that Lisa, an American tourist gone astray, has escaped from her city and country, from her friends and family, her job, her sexual identity, and her past. In the little society Cain creates for Lisa's idyll, men and women are equal, and homosexuality and heterosexuality are equally valid expressions of desire and love. From that premise, the story gives the reader a sojourn in a very different society and, along the way, examines Lisa's capacity for change. What she leaves behind of her past and what she will take into her future turn out to be as unpredictable as the new world she's discovered.
