The Pursuit of Thin Places: A Grief That Knows No Borders Rory MacLean's Geography of Heaven is a travelogue that doubles as a grief memoir.
After losing his wife to cancer five years ago, MacLean embarked on a journey across the world in search of "thin places" – locations where the veil between worlds is said to be porous.
His quest took him to sacred sites in Jerusalem, an ashram in India, a Native American community in South Dakota, and an ayahuasca ceremony in Peru.
