Left neglected - Lisa Genova

One typical morning, Sarah Nickerson, a woman in her mid-thirties, is late for work, racing in her car after dropping her kids off at school and daycare. She tries to phone in to a meeting she should already be at when she takes her eye off the road for a second too long. In that blink of an eye, all the rapidly moving parts of her over-scheduled life come to a screeching halt. Sarah suffers a traumatic head injury. Her memory and intellect are intact, but she has lost all interest in, and the ability to perceive, information coming from the left side of space. The left side of her world has gone. Sarah only eats the food from the right side of her plate. She can't see her watch, or her engagement diamond or her wedding ring. She tries to use a wheel chair but can only spin in circles as her left arm dangles by her side.
