Professor Greg Wrenn likes to tell his nature-writing students, "The ecological is personal, and the personal is ecological." What he's never told them is how he's lived out those correspondences to heal from childhood abuse at the hands of his mother.

Mothership: A Memoir of Wonder and Crisis is a deeply researched account of Greg turning to coral reefs and a psychedelic rainforest tea called ayahuasca to heal from complex PTSD--a disorder of trust, which makes the very act of bonding with someone else panic-inducing. From the tide pools in Florida where he grew up, to Indonesia's Raja Ampat archipelago and the Amazon rainforest, Greg takes his readers on a journey across the globe. In his search for healing from personal and ecological trauma, he dives into both the ocean and the psyche--and finds they have a lot in common.

Mothership is one man's audacious search for healing when talk therapy and pharmaceuticals did little to help. Written with prophetic urgency, Mothership ultimately asks if doses of nature will be enough to save us before it's too late--and what well-being means in a fracturing society on a dying planet.
