Unbowed:

Unbowed: A Soldier's Journey Back from Paralysis is the story of a dramatic recovery from diagnosed quadriplegia to a level of functionality rarely seen.
Billy Hedderman was body boarding on the Sunshine Coast, Australia on New Year's Eve 2014, when a wave dumped him into the sand. He broke his neck, back and suffered immediate spinal cord damage, paralysing him from the neck down. Lucky not to drown, Billy was rushed to Queensland's premier spinal injuries unit where he began the difficult road to recovery. Yet incredibly within seven months of his injury, the incomplete quadriplegic ran a 10 km race in Brisbane in under one hour.
Billy details how his previous life experience – such as service in the elite Special Forces unit Army Ranger Wing, and the death of his two close friends – have assisted in his mental toughness to prevail against all expectations. The book provides insight into Irish Special Forces from a recent serving tactical commander. Billy is currently a serving Captain in the Australian Infantry.
