At 22, Sage Rampion has led a strange and cloistered life. She's been homeschooled, and she's never watched TV, owned a phone or spoken to a man by herself. Everything she's seen, read and watched has been vetted for sexism by her grandmother Andrea, a professor and old school feminist. Lately, though, Andrea's feminist haven has begun to feel like a prison. Sage longs to connect with people her age, and is hating her chosen career. In defiance of Andrea, she grows her hair long, and it catches the eye of Ryan, an artist's model. The romance they build behind her grandmother's back prompts Sage to start asking questions. Who was the beautiful teenage mother who abandoned her as a baby? Why has she never got in touch, and why has Sage been told so little about her? But digging up the past means confronting Andrea about what she's been hiding and why. Taking her on makes Sage realise she needs to escape and seek the truth for herself. Not just to learn about her mother, but to figure out who she wants to be.
