A delightful investigation of the art of letter writing, Yours Ever explores masterpieces dispatched through the ages by messenger, postal service, and BlackBerry. Here are Madame de Sévigné’s devastatingly sharp reports from the French court, F. Scott Fitzgerald’s tormented advice to his young daughter, the casually brilliant musings of Flannery O’Connor, the lustful boastings of Lord Byron, and the prison cries of Sacco and Vanzetti, all accompanied by Thomas Mallon’s own insightful commentary. From battlefield confessions to suicide notes, fan letters to hate mail, Yours Ever is an exuberant reintroduction to a vast and entertaining literature—a book that will help to revive, in the digital age, this glorious lost art.
