Ecotone: Wayfaring on the Margins, a personal history of place, is written from the perspective of a teacher, naturalist, and feminist and uses the metaphor of the biological ecotone as the boundary where inner and outer landscapes of the woman/nature continuum meet.

In this book, Krall proposes a counter-narrative to the usual reading of marginality. In autobiographical narrative that rings with experience, she describes margins as rich as dynamic abodes, places of crossing over and transition as well as spaces of separation and alienation. In reinterpreting journeys and encounters, she maps the shared terrain of the personal, social, and natural fields of our lives. She draws upon Native American sensibilities about place, relationship, and the sacred, in order to deepen our understanding of human/nature bonds, to more fully develop respect and responsibility to others, and to heal the rifts that sometimes set humans at odds with other humans and non-human creatures and threaten life on earth.
