Disappointed with her job as a pharmaceutical rep and struggling with the decline of her long-term relationship, Grace is in no mood to pitch her company's latest antidepressant to another uninterested London doctor. But the disarming Dr. James - with his plans of studying Eastern medicine in Vietnam - stirs something in Grace, and soon she finds herself quitting her job, and her boyfriend, to follow her dream of becoming a yoga teacher.After months of training at the Bodhi Tree Foundation in California - where her fellow students are an eye-opening education in themselves - Grace returns to England ready for a new start. But nothing could have prepared her for the motley crew of students she amasses - from the octogenarian industrialist desperate for distraction to the American film star who uses yoga classes to conceal a scandalous affair. More and more, she finds herself relying on the letters she receives from Dr. James, his words hovering about her London life like a sweet promise.
