Lucy and Stephen Hawking

George and his best friend, Annie have been selected as junior astronauts - part of a programme that trains up young people for a trip to Mars in the future. This is everything they've ever wanted - they get to be a part of up-to-the minute space discoveries and meet a bunch of new friends who are as fascinated by the universe as they are.

But when they arrive at space camp, George and Annie quickly learn that strange things are happening - on Earth as well as up in our skies. Mysterious space missions are happening in secret, and the astronaut training they're undertaking gets scarier and scarier... 

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?

George and his best friend Annie haven't had any space adventures for a while and they're missing the excitement. But not for long...

Seriously strange things start happening. Banks are handing out free money; supermarkets can't charge for their produce so people are getting free food; and aircraft are refusing to fly. It looks like the world's biggest and best computers have all been hacked.

George and Annie will travel further into space than ever before in order to find out who is behind it.

George and Annie, with the help of their computer genius friend Emmett, must use the supercomputer to travel into space. First stop Mars, then on to the very edge of the known galaxy as they follow one clue after another on a fabulous treasure hunt across the cosmos.

Take a rollercoaster ride through the vastness of space and, in the midst of an exciting adventure, discover the mysteries of physics, science and the universe with George, his new friends next door - the scientist Eric and his daughter, Annie - and a super-intelligent computer called Cosmos, which can take them to the edge of a black hole and back again. Or can it? And who else would like to get their hands on Cosmos?

A funny and hugely informative romp through space, time and the universe.
