Aisha Moore is eight months pregnant. She's thrilled, and a little scared. Not least because her husband Jason hasn't quite wrapped his head around the fact.
Lucy is having her first child too. She has finally got her wish - although the circumstances aren't quite what she had hoped. Oscar will be a great dad though, won't he?
When the two women join the same baby group, they quickly become friends and before long they're confiding in each other.
Only there's one thing Lucy hasn't told Aisha. And while a baby may turn your life upside-down, a secret this big will change everything.
