In Catherine Lacey's ambitious second novel we are introduced to Mary, a young woman living in New York City and struggling to cope with a body that has betrayed her. All but paralyzed with pain, Mary seeks relief from a New Agey treatment called Pneuma Adaptive Kinesthesia, PAKing for short. And, remarkably, it works. But PAKing is prohibitively expensive and Mary is dead broke. So she scours Craigslist for fast-cash jobs and finds herself applying for the "Girlfriend Experiment," the brainchild of an eccentric and narcissistic actor, Kurt Sky, who is determined to find the perfect relationship--even if that means paying different women to fulfill distinctive roles. Mary is hired as the "Emotional Girlfriend" and is pulled into Kurt's ego-driven and messy attempt at human connection.
