No matter what he does or the decisions he makes, when death comes, Harry always returns to where he began, a child with all the knowledge of a life he has already lived a dozen times before.

Nothing ever changes - until now. As Harry nears the end of his eleventh life, a little girl appears at his bedside.

'I nearly missed you, Doctor August,' she says.
'I need to send a message.'

This is the story of what Harry does next, and what he did before, and how he tries to save a past he cannot change and a future he cannot allow. This is the extraordinary journey of one unforgettable character - a story of friendship and betrayal, loyalty and redemption, love and loneliness and the inevitable march of time.
