It’s no easy feat to top yourself at age 80. But this is exactly what Annie Proulx did last year with the release of her latest book, Barkskins. The novel tells a multigenerational tale, beginning with two pioneers in New France and the natural environment that supports them, which grows diminished and defaced with time. Even more staggering was the novel’s reception: reviewers called it “the masterpiece Proulx was meant to write,” and “perhaps the greatest environmental novel of all time.” With each passing book, Proulx proves herself to be an indispensable voice in American letters.
