Dixie is the youngest Diamond girl. She and her sisters - dreamy Martine, glamorous Rochelle and tough Jude - could hardly be more different, but their mum has always tried to teach them the value of sticking together.

Now Mum’s expecting yet another baby, and she’s convinced this one’s a boy. She insists they move to a bigger place - but it’s rough, dilapidated and filthy, and before they’ve even unpacked, Mum’s gone into labour! Can the Diamond girls pull together in time for her to come home? And will anyone spot Mum’s little secret but Dixie?
