Bella is a high-achieving, go-getting management consultant who seems to have it all. She's brilliant at her job, plays just as hard as she works and has a fantastic, sexy relationship with her husband Don. Then, she realises that something's missing from her life and decides to have a child (even though her husband isn't at all keen on the idea), and her ordered world is turned upside-down.

Bella's city slicker lifestyle doesn't go too well with morning sickness, swelling body and raging hormones. Suddenly it's all change - she's a sleep-deprived, emotionally-ravaged wreck, close to embarking on an affair with her former boss.
