In Hand on My Heart: A Canadian Doctor's Awakening in Afghanistan, Mayhew juxtaposes her experiences of Afghanistan as a foreign, female physician with her personal journey of questioning who she is as a professional woman in the 21st century. As she travels from one remote outpost to another, sharing cups of tea in secret, muddling through language barriers, and brokering trust with her patients, she finds her Western beliefs challenged and makes sense of her own struggles with gender roles. With curiosity and tenderness, Mayhew reflects on moments of disorientation, fear, wonder and joy. Hand on My Heart is a moving account that takes readers on an uncharted path into the mysteries of the human heart.
