Susan Rose is no average protagonist: she's scheming, promiscuous, plump, smart, funny, tender and entirely lovable. Like many working-class women in Victorian England she was born into a world that offered very few opportunities for the poor and unlovely. But Susan is the kind of plucky heroine who seeks her fortune, and finds it - with a little help from her breasts. As a professional wet nurse, she breastfeeds the children of women who can't or won't nurse their own babies. But when her own child is sold by her father, Susan embarks on a rescue mission.
