Weir wrote three books - each one more complex and stunning than the previous one. This Project Hail Mary is one of those science-fiction novels that makes you fell ignorant and needs a lot of attention to read it - but it's completely worth it. Best book of this kind - in my humble opinion. Maybe not compelling as the first one or adventurous like the secondo one, but great, intriguing, clever, and enlightening. The only thing I liked a little less is the tune of the main character while dealing with the de-facto leader of the world - even if that fits and works.
I guess I'll suggest (or gift) this book to a lot of people
