Elizabeth Marshall Thomas has spent a lifetime observing the natural world, chronicling the customs of pre-contact hunter-gatherers and the secret lives of deer and dogs. In this book, the capstone of her long career, Thomas, now eighty-eight, turns her keen eye to her own life. The result is an account of growing old that is at once funny and charming and intimate and profound, both a memoir and a life-affirming map all of us may follow to embrace our later years with grace and dignity.
