"You really should have kids." Hurtling toward 40-and still single and longing for children of her own-Kathleen doesn't need to be reminded that time is running out for her to turn her dreams for a family into reality. So she starts to consider a Plan B: becoming a single parent. But can she do it all on her own? And does she really want to? If only I could try it out, she thinks. For wouldn't an internship as a single mommy help her make major life decisions? And then....

In an open, thoughtful, and sometimes hilarious memoir, Kathleen shares what she learns while caring for her 15-month-old nephew, Jake, while his parents travel. With Jake, she experiences the realities of single parenthood, including a taste of the loving affection she craves, fierce tantrums that test her best aunting skills, moments of bliss amidst exploding poopy diapers and ongoing sleep deprivation, and ah-hahs that have her questioning whether she has wasted her life.

And that's just the start of her journey. Back at home, she unpacks and examines the societal baggage that led her to believe a woman's only true value is as a mother. Empowered by her experience, research, and introspection, she learns to embrace the different paths women choose, including the one she ultimately chooses for herself.
