What would happen to the world if the sun went out?

New epic sci-fi from Stephen Baxter, the award-winning author whose credits include co-authorship of the Long Earth series with Terry Pratchett.

By the middle of the 21st century, humanity has managed to overcome a series of catastrophic events and maintain some sense of stability. Space exploration has begun again. Science has led the way.

But then one day, the sun goes out. Solar panels are useless, and the world begins to freeze

Earth begins to fall out of its orbit.

The end is nigh.

Someone has sent us a sign.


This is a book that quite beautifully uses familiar SF tropes to explore how fragile we are as a species - and how robust and clever we can be too. 4.5 stars.
Galaxias is an unapologetic thought experiment...the true protagonist here is Baxter's invented and inventive cosmology.
