As a child, Vicky Hall never had the sort of family she wanted. The least important person in her new step-family, ignored by her mother in favour of her two younger half siblings, Vicky was always an afterthought.

Susie did something that she knows she will always regret: giving her baby son up for adoption, to keep her infidelity secret from her family.

And Danny, Susie's husband, adores her but has always sensed something wrong at the heart of their marriage.
