The true story of Peter Marshall, a champion squash player who, at the peak of his career, was struck down with chronic fatigue syndrome, an illness with no treatment and no known cure. After an agonising period of recovery, he was forced to decide between the huge insurance payout or risking everything on an uncertain comeback attempt. If he played just one professional match, he would forfeit the money. He chose to play. From the elation of victories to the despair of being too weak to walk across a room, the author examines chronic fatigue syndrome, and offers one man's battle as a beacon of hope to other sufferers.
