Though it never goes for the gross-out effect, this memoir is not for the squeamish. "You begin to learn to heal the living by dismantling the dead," says Montross, and though her recollections encompass all of her medical training, the narrative backbone of the story is her semester-long dissection of a human cadaver, from opening up the ribcage to removing the brain from the skull. Montross was a poet and writing teacher before she decided to become a doctor, and she peppers her account of the dismantling of her cadaver, Eve — so named because she has no belly button — with arresting imagery: to test the heart's semilunar valves ("little half-moons that work passively and without musculature"), she and another student take the organ to a sink and run tap water through it. Performing her own dissection leads Montross to explore the history of studying anatomy through corpses, which brings tantalizing detours to medieval Italian universities and saints' shrines. But she also recounts her earliest encounters with living patients, such as a heart-wrenching consultation with a man suffering from Lou Gehrig's disease, who can communicate only by blinking. Her thoughtful meditations on balancing clinical detachment and emotional engagement will easily find a spot on the shortlist of great med school literature. (June 25)
