What can prairie voles teach us about love? A lot, as it turns out. Prairie voles have the most passionate long-term relationships on Earth. They are programmed for success, demonstrating commitment to their life partners, excellent parenting skills and healthy sex lives. Andrew G. Marshall combines new scientific research into the voles' success, the latest developments in human neuroscience and his twenty-five years' experience as a marital therapist to create a six-step programme that puts lovemaking at the heart of a strong relationship.
