I've seen her a thousand times. Running through the blue shadows in the rain. Stopped by a screech of brakes and my voice shouting. Stopped by the sudden boom of my heart.

On a quiet road just outside London, in the blue half-light of dusk, a car accident will change the lives of two families forever.

Jack Philips is a happily married policeman with two small daughters, but the consequences of the accident will force him to reassess everything he loves - and to confront long-buried secrets in his past.

For Lisa Jenkins, the devastation caused by the accident seems almost unbearable. Until she discovers an inner strength she never knew she had - and the courage to change her life completely.

In this heartbreaking but ultimately uplifting debut novel, Elizabeth Diamond explores the ripple effects of a single moment of tragedy - the journey from guilt to peace, from vengeance to forgiveness, from grief to hope - and even, ultimately, to joy.
