Ten years have passed since Roz committed the ultimate sin of motherhood: she left her family behind when she walked out on her husband. Now, drawn back into that world by the death of their redoubtable grandmother, Nan, Roz finds herself embroiled in the lives of her grown-up children, laid-back Jamie and sexually energetic Zoe. And she realises that they have returned to her so that they might leave her in the proper scheme of things. Rather than she leaving them.
