Uma Gnuderson has a world full of questions: How can I save my home from being sold? Will my dad ever start talking again? And how do alpacas get drunk? But since her mum died, Uma's life has been short on answers. Until one day she finds a mysterious Bluetooth earpiece, and starts to ask it questions. And it answers them. All of them. It knows everything, from the capital of Mongolia to the colour of her headteacher's underpants. The earpiece is actually an incredible high-tech artificial intelligence called Athena. Through Athena, Uma suddenly has the answer to every question she can imagine—and she's going to use them to save her home and her father. Along the way, Uma will have to confront the sinister inventor who will stop at nothing to get Athena back—and face up to the fact that not all questions have answers . . .
