When they first met, Gail Caldwell was a book critic for the Boston Globe and Caroline Knapp had just published Drinking: A Love Story. They could have been competitors but instead became best friends. The recovering alcoholics, both devoted dog lovers, walked the Massachusetts woods together, rowed the rivers and talked. When Caldwell bought a house, Knapp carried her over the threshold. And then Knapp got cancer. Heartbreaking but never maudlin, Let's Take the Long Way Home is a testament to the power and beauty of mature friendship and the most powerful memoir about loss since Joan Didion's Year of Magical Thinking.
