Joey's parents love rescuing things and making them beautiful – their house is full of things made from driftwood, old glass and shells from the beach. Which is why the scraggy kittens the girls find in a bin at school end up living there. And when Paul moves in as Joey's foster brother, everyone thinks that maybe he needs rescuing too. But nobody knows quite how badly. At first, it's great – Hannah's brother befriends Paul, and the four of them hang out together. But then things start to go wrong. Paul is being bullied. Subtly at first – but quickly it gets dangerous. People aren't like driftwood or abandoned kittens and Hannah doesn't know how to rescue him. Paul doesn't want to be rescued – but with help, he can find a way to save himself.

    It now has 600,000 to a million page hits daily. Every now and then, Munroe would get emails asking him to arbitrate a science debate. 'My friend and I were arguing about what would happen if a bullet got struck by lightning, and we agreed that you should resolve it . . . ' He liked these questions so much that he started up What If. If your cells suddenly lost the power to divide, how long would you survive? How dangerous is it, really, to be in a swimming pool in a thunderstorm? If we hooked turbines to people exercising in gyms, how much power could we produce? What if everyone only had one soulmate?When (if ever) did the sun go down on the British empire? How fast can you hit a speed bump while driving and live?What would happen if the moon went away?In pursuit of answers, Munroe runs computer simulations, pores over stacks of declassified military research memos, solves differential equations, and consults with nuclear reactor operators. His responses are masterpieces of clarity and hilarity, studded with memorable cartoons and infographics. They often predict the complete annihilation of humankind, or at least a really big explosion. Far more than a book for geeks, WHAT IF: Serious Scientific Answers to Absurd Hypothetical Questions explains the laws of science in operation in a way that every intelligent reader will enjoy and feel much the smarter for having read.
