There's no pain, no theatrical agony. No screaming, no shouting.

The kill shot is catastrophic and conclusive. I slump silently on to my knees and topple forward, head first, into the dirt. The lads have seen enough death to assume mine is instantaneous.

The lights are out. That's him gone. Toby Gutteridge was only 24 when he was shot through the neck while operating behind enemy lines in Afghanistan.

He survived despite not breathing for at least 20 minutes. Back in the UK, doctors recommended that his life support machine be switched off, but with the defiant spirit that would define his recovery, Toby pulled through. Now quadriplegic, capable of movement only with his head, Toby has rebuilt his life.

His is an extraordinary story of survival against overwhelming odds, and of the power of the human spirit to overcome extreme adversity. Brutally honest and authentic, he builds a compelling picture of the type of person produced by the Special Forces system, and tells of how one split second changed the course of his life forever. Powerful and inspiring, Never Will I Die is a universal story of life triumphing over death.
