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 h

“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):

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

Like most people, I was first introduced to Weir’s writing through The Martian. His latest novel is a wild tale about a high school science teacher who wakes up in a different star system with no memory of how he got there. The rest of the story is all about how he uses science and engineering to save the day. It’s a fun read, and I finished the whole thing in one weekend.

I think my job is to solve the Petrova problem.

Guess I was wrong to resist reading this for months. Thing is, I liked The Martian and really really disliked Artemis.

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.

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.

Yes yes yes. Good book. Good book. Good book.

Ryland Grace, the coolest middle school science teacher ever, slows opens his eyes to discover himself on a spaceship. However, he can't remember his name or his exact mission. Will this scientist discover and fulfill his mission in time to save humanity?

Project Hail Mary had a very conversational tone, the prose was so smooth and not clunky, and I highly, highly recommend the audiobook. The energy and enthusiasm of the narrator was infectious. Proje

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 have read this year. I

When Ryland Grace awakens from a coma, he discovers he is on a spaceship. He doesn't know why, or how, in fact, he can't even remember his own name.

Checking his surroundings, Ryland quickly determines he is alone; the two other crew members evidently not making it out of their comas. Well, shoot, not good.

Figuring he has nothing but time, Ryland sets about investigating his surroundings in the hopes of determining his purpose for being there.

As his memories slowly return, he understands the impo

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

Good old flashback amnesia who where what why wtf.

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.

region, it got bogged down by too many flash-fires while our protagonist, Ryland Grace, the ultimate Gary Sue and the purveyor of all things Space/Biology/Physics/Chemistry/Engineering/Math/Music/Language/Etc, got progressively more facetious and irritating.

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

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

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 turns out that I have very little brain for physics: I will understand it about as long as it takes a highly competent teacher to explain it to me and no longer.

Andy Weir cannot write and I'm tired of people pretending he can.

First, let's talk about characters- well, there is no character here. I only see a vague man-shaped science textbook in an astronaut suit. Wait, let me put my glasses on. OH, I know him. Quirky, wisecracking, nerd who likes space.. It's Mark Watney.

Mark Watney's alone in the space, again. Oh. Can you believe his luck? Anyway, he's alone and he's quirky and nerdy and that's all very nicely boring but hold on.. there are flashback s

In life, I have one favorite thing and one least favorite thing.

My favorite thing is laughing. I am possibly the easiest laugh in the entirety of the human population. I chuckle through every interaction, I giggle at every standup special I've ever seen, I have been known to grin at commercials, greeting cards, and just about all paragons of humorlessness. I love this about myself, both because it makes daily life fun and because when I date men I love watching the horror as they realize that th

I remember what I tell my students: If you’re upset, take a deep breath, let it out, and count to ten. It dramatically reduced the number of tantrums in my classroom.

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.

I am upset that this book was just not the right fit for me and I realize that there are many others who did and
Woah! This book was excellent!

Sure, it is loaded down with science and math. And, at times, the science and math can slow down the narrative a bit. But there is no need to understand the math and science to enjoy this unconventional sci-fi story. And, in a world flooded with sci-fi literature for the past 75 years or so, it is kind of amazing to find a fresh new take. (Note: I am sure that someone who is more well read in sci-fi is going to read this review and give some examples where this is n

Project Hail Mary rises like a phoenix from the ashes of the steaming dumpster fire that was Andy Weir’s unfinishable Artemis.

Weir’s return to form brings us a science teacher, Ryland Grace, who's thrust into an effort to save Earth from a raging space algae that’s draining the sun. (Kinda like if Walter White had gone good instead of breaking bad with a meth empire.) He wakes up alone on a spacecraft and has to remember how and why he got there, not to mention how he’ll get home.

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

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.

But gradually, through a series of flashback memories, Ryland Gra
