Natalie is a magazine journalist whose lover is a widower with three children - three children who absolutely do not want a new woman in their life. After a disastrous first meeting‚ Natalie turns to her best friend Clare for advice.
Clare‚ a single mother and teacher‚ tries her best to counsel Natalie‚ but suggests she should talk to her younger sister‚ Lily‚ who is in the same boat aged only 23.
After a reluctant coffee‚ the women concede that they've enjoyed themselves. Then‚ to Natalie's shock‚ one of her colleagues refers a friend to her 'stepmothers' support group' - and the group is born...
As the story unfolds‚ five very different women share their hopes and fears‚ their love lives‚ their ambitions - and their feelings about their new family. Through it all‚ their new friends provide a sympathetic ear‚ advice and someone to laugh with. You can't choose your family - but you can choose your friends.
