When 38-year-old New Yorker writer Ariel Levy left for a reporting trip to Mongolia in 2012, she was pregnant, married, financially secure and successful on her own terms. A month later, none of that was true. Levy picks you up and hurls you through the story of how she built an unconventional life and then watched it fall apart with astonishing speed. Like much of her generation, she was raised to resist traditional rules --- about work, about love, and about womanhood.
