From bestselling and award-winning author Alice Mattison comes a breathtaking new novel following two best friends from Brooklyn, exploring the way in which the world and their lives change over the course of the 20th century. The deft literary touch that readers have grown to love in novels such as Nothing Is Quite Forgotten in Brooklyn and The Book Borrower, as well as story collections such as In Case We're Separated, combine in a marvelous narrative of friendship and family, with rich, complicated characters who grow and change together over the course of seventy-five years. Fans of generational stories such as East of Eden, or novels of friendship such as The Amazing Adventures of Kavalier and Clay, will be swept away by the intimate beauty of Mattison's latest triumph, When We Argued All Night.
