This final explosive adventure in the bestselling series created by Lucy and Stephen Hawking sees George take on huge questions about time, relativity and the future of the universe. Including non-fiction content from leading experts on subjects from artificial intelligence to climate change, this is the perfect read for any curious young mind.

When George finds a way to escape the spacecraft Artemis, where he has been trapped, he is overjoyed. Surely now he can return to Earth.

But when George touches down, he knows immediately that something is wrong. There’s a barren wasteland where his home town used to be, intelligent robots roam the streets, and no one will talk to George about the Earth that he used to know. With the help of an unexpected new friend, can George find out what - or who - is behind this terrible new world, before it’s too late?
