Can happiness bring about the end of the world? An unputdownable thriller from bestselling author Neal Shusterman. A new virus is spreading across the world – and whoever gets infected becomes infinitely happy. No stress, sadness, depression or greed. But the rich and powerful soon realise that you can't make much money from happy people, and they start spreading information that happiness is dangerous and will plunge the world into chaos. But what is the truth? And what role will two teenagers play in the whole situation when, by mistake, they are given the chance to influence the fate of all humanity? Recommended for ages 13+
