Followers of Pet Jeffery will love this latest, expertly crafted and heart-warming full-length novel of age regression, tempered with the inevitable spankings that all naughty girls should receive. It begins with Penelope Wells, an unmotivated and unhappy 23-year-old Leicester girl. After failing her A-levels, instead of pursuing a career, she moves in with Timothy and puts up with his infidelities until he moves his new girlfriend in and kicks Penny out. Returning home to Mum doesn't work out, so Penny persuades her cousin Rachel to loan her some money, and rents a squalid bedsit. Flicking through an upmarket magazine, Penny spots an ad for a companion and manages to get an interview. The job is not what she expected, as the lady of the large and expensive house in London, Mrs Browning, is really looking for a daughter... and Penny fits the bill perfectly! Looking much younger than her actual age, Penny has no real focus in life and no-one to care for her. Mrs Browning becomes her mama, taking the vulnerable and undisciplined girl into heart and home. But Mama can be very strict as well as loving, and she is a firm believer in the efficacy of corporal punishment.

Although Penny often has a sore bottom, she loves her new mama and fully appreciates Mama's brand of loving discipline. Her life is changed for the better. Mama treats her as a 14-year-old, and Penny becomes accustomed to acting and dressing a younger age, and delights in re-experiencing her teenage years. She makes friends with girls in similar circumstances to herself, and they regularly get up to mischief and pay the price on their bare bottoms. Mama even gives her new daughter a new name, and as Penny blends into Virginia (Ginny) her life is enriched beyond her wildest dreams.
