Twelve-year-old Ming Qong is convinced that girls must have changed the world, even if they are rarely mentioned in history books. So when Ming gets the chance to go back in time she imagines herself changing destinies from a glittering palace or explorer's ship, but instead, she ends up in Australia in 1898, living a tough life as Flo Watson on a drought-stricken farm. Luckily, Ming is rescued by Flo's Aunt McTavish. Wealthy Aunt McTavish belongs to Louisa Lawson's Suffragist Society, who are desperately and courageously fighting for women's rights. And Ming is determined to get involved, to make a difference. But change is never easy, so how can one girl change the world?
