On the night of April 9, 1997, Warren Macdonald, a fit and experienced bushwalker, set out to climb Mount Bowen on Hinchinbrook Island, an unspoiled tropical paradise off the Australian coast. These would be his last steps as a fully intact human being: a freak rock fall pinned him for two days alone under a one-ton boulder, resulting in a double leg amputation. A Test of Will is a story both tragic and inspiring, conveying the horror of what happened and the extraordinary spirit that helped Macdonald survive a seemingly impossible ordeal.
