Emily is the ringleader for her school podcast, Cedarview Speaks - Sponsored by CoastFresh! But her plans for middle-school fame and social media influence are derailed when Amelie joins her eighth-grade class. The new arrival has a seemingly endless supply of confidence and a gift for leading people. Or leading them astray, as far as Emily's concerned. Emily puts her old-fashioned sense of etiquette into practice. Rather than confronting Amelie, she focuses her energy on creating a podcast story about an upcoming climate march. But her story is censored by the school principal. When she protests, Emily gets cut from the podcast crew... and Amelie takes her place! Can Emily use her influence to spread the news of the climate march, reclaim her place on the podcast team and expose the flaws of CoastFresh? Can she balance her impeccable manners with twenty-first century activism? And how will she ever manage to work alongside Amelie? With a light touch and plenty of humour, Emily Posts explores issues of social media, influence, corporate sponsorship... and the fraught waters of middle-school friendship.
