Sometimes, one moment is all it takes . . .

Telling the story of the week following a fateful train journey, One Moment, One Morning by Sarah Rayner is a stunning novel about love and loss, about family and – above all – friendship. A stark reminder that, sometimes, one moment is all it takes . . .

The Brighton to London line. The 07:44 train. Carriages packed with commuters. Then, abruptly, everything changes: a man has a heart attack, and can't be resuscitated; the train is stopped, an ambulance called.

For at least three passengers on the 07:44 on that particular morning, life will never be the same again.

Lou witnesses the man's final moments. Lou and Anna share a cab when they realize the train is going nowhere fast. Anna is Karen's best friend.

And Karen? Karen's husband is the man who dies . . .
