Harry August is on his deathbed. Again.

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.
