Vintage Books, 2018. Paperback, 326 pp. In the spring of 1983, Terry Tempest Williams learned that her mother was dying of cancer. That same spring, Great Salt Lake began to rise to record heights, threating the Bear River Migratory Bird Refuge and with it the herons, owls, and snowy egrets. One event was nature at its most random, the other a by-product of rogue technology. This book transform tragedy into a document of renewal and spiritual grace, resulting in a work that seems certain to become a classic in the literatures of women, nature, and grieving.
