Struck with Parkinson's - a debilitating, degenerative disease - at the height of his fame, Michael J. Fox has taken what some might consider cause for depression and turned it into a beacon of hope for millions.

In Always Looking Up, Michael's Sunday Times bestselling memoir, he writes with warmth, humour and incredible honesty about the journey he has undertaken since he came to terms with his condition.
