The mother's bond

What would you do if the child you secretly gave up came looking for you? Kathryn Casey lives a charmed life in affluent Chester-le-Street.

Her husband adores her, her children are bright, well-behaved and beautiful and her world is orderly and predictable.

Until one day she walks into her kitchen - and sees the son she gave up for adoption twenty-one years ago.

Kathryn was once Kelly, a girl who lived on one of the roughest estates in the North and got pregnant at sixteen.

She'd tried her hardest to keep her baby, but without any help, it all got too much for her.

She's never told her husband about her past. Now her child is in her home. But what does he want? And can Kathryn help him without giving away the secret she's buried for so long?
