Cheryl’s best female friend. Lisa lives in Portland and is the one to organize and send Cheryl’s care packages to the various stops Cheryl is making along the PCT. Though Lisa is only glimpsed in flashbacks for most of the book, it becomes evident that she is a kind, thoughtful, devoted friend—one who has seen Cheryl through her darkest moments and has remained loyal and committed to her in spite of her struggles with self-destructive behavior. Cheryl was always told growing up that blood was thicker than water, but Lisa is one of the people in her life who challenges that axiom through her sisterly devotion and love.
