A brilliantly funny story of what happens when a galactic princess moves in next door and almost brings about the end of the world. Exciting new fiction from the bestselling, award-winning author of My Brother is a Superhero. Gavin's got a new neighbour and she's really annoying. Niki follows him everywhere, bosses him about, and doesn't care that her parents will obliterate Earth with their galactic warships if she doesn't stop running away from them. Can Niki and Gavin sort out the alien despots (aka Mum and Dad) and save the planet? Possibly. Will they become friends along the way? Doubtful.
