On the eve of her 70th birthday, Canadian writer Margaret Atwood set out on an international tour criss-crossing the British Isles and North America to celebrate the publication of her new dystopian novel, The Year of the Flood. Rather than mount a traditional tour to promote a book's publication, Atwood conceived and executed something far more ambitious and revelatory--a theatrical version of her novel. Along the way she reinvented what a book tour could (and maybe should) be. But Atwood wasn't selling books as much as advocating an idea: how humanity must respond to the consequences of an environmentally compromised planet before her work of speculative fiction transforms into prophesy.
