His mother walked across America in the seventies. Her past fascinates him. Her faith confounds him. They embark on a 5,000-mile journey to discover how families can stay together when beliefs are pulling them apart.

When his mother, Barbara, turns seventy, Jedidiah Jenkins is reminded of a sobering truth: Our parents won't live forever. For years, he and Barbara have talked about taking a trip together, just the two of them. They disagree about politics, about God, about the project of society - disagreements that hurt. But they love thrift stores, they love eating at diners, they love true crime, and they love each other. Jedidiah wants to step into Barbara's world and get to know her in a way that occasional visits haven't allowed.

They land on an idea: To retrace the thousands of miles Barbara trekked with Jedidiah's father, travel writer Peter Jenkins, as part of the Walk Across America book trilogy that became a sensation in the 1970s. Beginning in New Orleans, they set out for the Oregon coast, listening to podcasts about outlaws and cult leaders - the only media they can agree on - while reliving the journey that changed Barbara's life. Jedidiah discovers who Barbara was as a thirty-year old writer walking across America and who she is now, as a parent who loves her son yet holds on to a version of faith that sees his sexuality as a sin.

Along the way, he peels back the layers of questions millions are asking today: How do we stay in relationships when it hurts? When do boundaries turn into separation? When do we stand up for ourselves, and when do we let it go?

Tender, smart, and profound, Mother, Nature is a story of a remarkable mother-son bond and a moving meditation on the complexities of love.
