Wanderlust : a love affair with five continents / by Elisabeth Eaves.

Enhanced descriptions from Syndetics:

Spanning 15 years of travel, beginning when she is a sophomore in college, Wanderlust documents Elisabeth Eaves's insatiable hunger for the rush of the unfamiliar and the experience of encountering new people and cultures. Young and independent, she crisscrosses five continents and chases the exotic, both in culture and in romance. In the jungles of Papua New Guinea, she loses herself -- literally -- to an Australian tour guide; in Cairo, she reconnects with her high school sweetheart, only to discover the beginning of a pattern that will characterize her life over the long-term: while long-distance relationships work well for her, traditional relationships do not.

Wanderlust, however, is more than a chronological conquest of men and countries: at its core, it's a journey of self-discovery. In the course of her travels, Eaves finds herself and the sense of home she's been lacking since childhood -- and she sheds light on a growing culture of young women who have the freedom and inclination to define their own, increasingly global, lifestyles, unfettered by traditional roles and conventions of past generations of women.
