In this fifth and final book in The Girls Who Changed the World series, Ming Qong discovers who she is, and that she, too, will change the world.

Herstory, History's sister, has sent Ming all through history to meet girls who have changed the world. But now, Herstory promises to show Ming something of her own past: her long-lost mother.

So when Ming washes up on the shores of Nantucket Island in 1836, she is confused. She is saved by the elderly Mrs Sloe and wealthy Miss Reynolds, but there is no sign of a woman who could be her mother.

The island is home to Maria Mitchell, who, at seventeen, has already published her first papers on astronomy, and will go on to inspire universities around the world.

Maria's future holds extraordinary promise and fame. But what about Ming?

Ming's time on Nantucket will revolutionise all she believes about herself, her family, and Herstory too.

In this final book in the Girls Who Changed the World series, Ming Qong discovers who she is, and how she, too, will change the world.
