It's 2041 and climate change has irreversibly altered our planet andlifestyles. Nova and Joule are fourteen-year-old twins whose scientist parents have recently uprooted the family from their urban home and moved to the country on a year-long research assignment, studying the effects of GMO 'SuperCrop' farming on the environment in the final regulatory phase before global expansion. Surrounded by nature and quiet, open spaces, shy, bookish Nova is in heaven. But Joule - whose life's ambition is to be famous and reach a million Hollagram followers - is desperate to escape. One day, Joule gets her wish, although not in a way anyone ever expected. In an instant, she's gone - swallowed up by a mysterious sinkhole under her bedroom floor. Suddenly twinless, Nova is forced to step in and lead the search for her missing sister. But can she face her fears and figure out what caused the sinkhole in time to save Joule?.
