Project Hail Mary

My younger daughter is a big fan of space, and she loved Andy Weir's previous book (and the movie) The Martian, so she was very excited both for this novel and the film which has just been released, starring another favourite, Ryan Gosling. (She went to see a preview of Project Hail Mary at IMax, and we are going together to see it again next week.)

Andy Weir is very good at writing about science and using science to solve specific problems. There's no hand-wavery here (not that I can detect, anyway). In The Martian, we saw a marooned astronaut figuring out how to survive on Mars. Project Hail Mary widens the scope of the drama to put the entire Earth in jeopardy, when a light-feeding life form starts devouring the sun. The whole of humanity unites to solve this problem (pity we can't seem to do this for the climate crisis) and it ends up with, again, a single astronaut, Ryland Grace, far, far out in space, having to work out what to do to save the world. This time our sole survivor is joined by an extra-terrestrial who looks like a spider, uses hearing instead of sight as their primary sense, and 'speaks' with sound, who has come from his own home world to solve the same emergency, which he calls, 'bad bad bad.'

Some of my favourite scenes in the novel are the ones where Grace and Rocky are working out how to communicate with each other and work together, despite the differences in their physiology. It's lucky that Rocky's culture is broadly compatible with that of an American high school science teacher and they can get along so well. I had a quibble when Grace noted that Rocky calls him the Eridian equivalent of the word 'grace,' which, given the religious and historical freight of that word in English, raised more questions about Rocky's planet than could possibly be answered.

Weir does an excellent job of continually raising the stakes and throwing obstacles at his characters; he also skilfully uses flashback and Grace's initial amnesia to reveal the backstory of events on Earth. Honestly I was more interested in the Rocky/Grace timeline but it was all fun. I can't wait for the movie, which my daughter reviewed as 'amaze! amaze! amaze!'
