Project Hail Mary by Andy Weir

4.0

Another very entertaining space romp from Andy Weir, author of [b:The Martian|18007564|The Martian|Andy Weir|https://i.gr-assets.com/images/S/compressed.photo.goodreads.com/books/1413706054l/18007564._SY75_.jpg|21825181]. The main character has all the same charming personal characteristics of The Martian's hero, too; I love this style, and if you liked The Martian, you're very likely going to like this one, too.

The Earth envisaged here is a present-day Earth, where we find that something is causing the light emitted by the sun to drop. At the moment, the drop is fractions of a percent, but it's increasing exponentially, and climate models predict that in about 30 years the Earth will get beyond the point of being able to sustain human life at any scale. Bad news all around.

Ryland Grace, our hero, is one of the first to realise what's going on, and is recruited as part of the global task force to work out what's going on, and come up with plans to fix it. The first part of the story alternates flashbacks to when all this is going on with Grace emerging from an induced coma on a spaceship, light years away from Earth. He's lost his memory, but through the flashbacks - and his own smarts - he works out what's going on. He is on a last-ditch mission that's attempting to find a fix to the problem. And he's all alone - his fellow astronauts died during the induced coma.

Lots more unfolds, and it's told with lots of verve and nerdy detail, which I loved. There are maybe one or two wobbly bits of plot furniture if you're being picky, but overall I enjoyed it greatly, and it gets four well-deserved stars.
