Ryland Grace is the sole survivor on a desperate, last-chance mission--and if he fails, humanity and the earth itself will perish.

Except that right now, he doesn't know that. He can't even remember his own name, let alone the nature of his assignment or how to complete it.

All he knows is that he's been asleep for a very, very long time. And he's just been awakened to find

Happy book birthday to the most anticipated sci-fi novel of the year!🥳

I can proudly honestly excitedly announce a GRANDIOSE WINNER now!

I know my overcooked brain cells don’t have enough capacity to absorb every complicated, detailed, elaborated scientific facts and fantastic world building which amazed me at least thousand times but I fell so hard what I could understand which is enough for me to enjoy this book!

It truly hugged my inner weirdness and nerdy proportionally!

Thoroughly imaginative, scientifically sound, and emotionally stirring, Project Hail Mary slayed me and is destined to become one of my all-time favorite books!

Ryland Grace wakes up in a spaceship light years from Earth. The problem is he doesn't remember who he is or what he's supposed to do. But whatever it is, it must be important, or he wouldn't have been sent on this mission with two other astronauts. Unfortunately, neither of them survived the journey, so he is all alone. And he is Earth's

Andy Weir is back with a new novel suitable for fans of The Martian.

“I’d have to do the math to know for sure but — I can’t help it, I want to do the math right now.”
This book is half science experiments, half wacky buddy comedy — and it just works so so so well! That nerdy glee I felt on every page of The Martian is back full force. By golly*, I am so gosh-darn* happy right now. Geez and fudge and Holy Moly!*. (Yeah, this book’s protagonist tends to sound like he’s 85 — he’s just not a foul-mouthed sort of a scientist):

Project Hail Mary by Andy Weir 

Project Hail Mary gives us the story in several timelines. It starts with Ryland Grace waking up in a room, tubes and lines running from his body, mind groggy and memory slow to return. In fact, it's like he has amnesia. His two roommates died at some much earlier date, their bodies now mummified. He has no idea where he is, who the other people were, what he's supposed to do now. But there is a computerized voice urging him to "eat" slop from a tube and telling hi

I loved the Martian, loved Artemis but Project Hail Mary was everything!

The book starts out with some cray and you don’t want to put it down because you want to know what the hell is going on!!

The story goes back and forth from the present to the past and how it all came to be.

My favorite part was when Rocky came onto the scene. I love him so much and if you read the book and don’t love him, there is something wrong with you.

The book has plenty of science, humor, edge of your seat

I love accessible sci-fi and I truly do not know how Andy Weir makes his books so readable and yet so comprehensive in terms of the science. This is a page-turner. It’s so much fun! Ryland wakes up alone on a spaceship and doesn’t remember who he is, what his mission is, or even where in the universe he is. Everything just gets wilder from there.

okay. so i almost wrote off AW after the disaster that was ‘artemis.’ but im so glad i gave him another chance, because this was really fun.

im nowhere near smart enough to understand all of the technical and scientific dialogue in this (im also too lazy to fact check and do any research on the concepts discussed), but that did not stop me from enjoying this. and i honestly wasnt expecting much, so the fact that alien lifeforms are present, by way of a precious alien named rocky, really surprised

(Throwback Review) I have read two books by the same author simultaneously a few times in my life. But I never had such a contrasting opinion about two books like this book and Artemis. I liked the book The Martian by Andy Weir. So I was sure that I was going to love both these books. But I was totally mistaken and was off to a roller coaster ride with these books. Andy Weir perfectly showed us what exactly failing forward means. Artemis was an utter disaster and one of the worst books I hav

Thirty years. I looked out at their little faces. In thirty years they’d all be in their early forties. They would bear the brunt of it all. And it wouldn’t be easy. These kids were going to grow up in an idyllic world and be thrown into an apocalyptic nightmare.
They were the generation that would experience the Sixth Extinction Event.

It’s alarming to wake up from a coma in completely unfamiliar surroundings, tethered to a bed by tubes and electrodes, with a computer voice quizzing you and robotic arms controlling your movements. It’s even more disturbing when you realize that you have no recollection of your name or your past life, and that there are two long-dead bodies in the room with you.

Andy Weir's latest smart sci-fi thriller, set in space, illustrates his trademark charm, humour and wit despite humanity on Earth facing extinction as an unknown organism, Astrophage, is discovered to be stealing energy from the sun en masse, thereby threatening life on earth in the not too distant future. In a story heavy on science and technology, which might not appeal to some readers, but which I found interesting, Dr Ryland Grace is a scientist who gravitated towards high school teaching af ...more

I requested this book just based on the fact that I enjoyed the movie “The Martian”. I wasn’t sure what to expect.

The beginning of the book is a little confusing, mainly because our narrator has just woken up from an induced coma and does not really know where he is, why he is there and who the two CORPSES ARE THAT ARE IN THE ROOM WITH HIM!!!!!!!! He is having trouble moving, speaking, etc and is connected by so many IV’s and electrodes that he is completely incapable

Some people read a book more quickly the more they enjoy it. I'm the opposite. If I read a book slowly, it almost always means I love it. 

I want to savor every word, miss not one detail. I often re-read paragraphs or pages just to ensure I caught everything.

This book while not as good as The Martian it was much better than Artemis. I was worried about reading it after my bad experience with Artemis so I honestly didn’t have high expectations, I’m glad to say I ended up enjoying this book a lot -for the most part.

In case you don’t know the premise, some alien microorganisms (astrophage) are eating the sun’s energy simply put which will make Earth colder and lead to another ice age. The 8th-grade teacher is a scientist who finds himself invo

Sadly, although I am truly a big fan of Andy Weir, I have to say this book was not a success for me. It seemed to be too much centered in the science/math vein and I found myself wondering how a Junior High School teacher could achieve the prestige of being chosen for this mission. His "aw shucks" attitude also seemed to be a tad out of character for a man entrusted to save the planet.

And we're back. I loved the Martian and I was pretty okay with Artemis, but Project Hail Mary is a slam dunk. Weir kills it here.

This is a callback to all the best science porn we love in SF. Clear descriptions, great discoveries, and plenty of normal disorientation to go along with the numerous setbacks surrounding these crazy-cool characters.

I suppose I like the snark best of all, but the science, from an extinction-level event, massive resources being thrown at the problem, and then the outri

"Project Hail Mary" is an incredible unputdownable science fiction novel. But it's a far from what most might expect from a space opera. This is a science geek's version of astronaut life. It breaks all the rules of what makes a science fiction novel a great read and offers us scientific theory after scientific theory as Grace tries to solve one mystery after another. You never stop cheering Grace on as he figures out one answer after another only to be befuddled by reality. McGyver would be qui ...more

Having read The Martian and seen the movie, I was anxious and excited to read Project Hail Mary. First, let me explore some of the problems causing mixed reviews. It is very heavy on science and technology. I thought the explanations by Andy Weir were difficult to follow for anyone without a strong background in mathematics, physics, chemistry or astronomy. Still, the author did this as well as possible. I found I did not need to fully follow the explanations to be along on the wild ride through ...more

If you're a fan of sci-fi space operas and don't mind the science part of them, then stop reading this review and go read Project Hail Mary. Seriously.

At first, the premise might sound a little too close to The Martian, but it will quickly become clear that it's also very different - the stakes are so much higher in this one. Yes, it manages to capture the essence of what made The Martian special, yet it doesn't feel like a copy.

The biggest problem for Andy Weir is that he wrote The Martian. Every other book he writes will be compared to it and, let's face it, have little chance of being able to stand up to it. It's like lightning striking twice - possible, but not probable.

Sadly, I can't say much about the plot, or the part of the story that I absolutely loved the most, without spoiling anything, so I'm going to keep this review brief.
