I am a huge fan of Andy Weir, author of the Martian. Project Hail Mary is an excellent science-themed page-turner.
Title: Project Hail Mary
Author: Andy Weir
Pages: 476 pages
Rating: 4 of 5 stars
Meet male, caucasian astronaut. He's adrift in space, destination unknown, mission unknown, name unknown. Weir rapidly builds our hero up in just 2 chapters without annoying the reader with the fact that he has no name or purpose. He also threads the needle with the hero to prove he isn't a recast version of Mark Watney from The Martian.
Our astronaut is quickly introduced to two different problems. One is immediate, an inflated catheter in his... ah... you know. And the second more distant, an infrared glow around Venus. (Hey, I didn't write it. Well, I did but...) The second becomes the major problem of the story, no matter how immediate the other problem would be. Something is drawing energy from the Sun to the orbit of Venus. The sun isn't dying but the dimming will kill every living thing on Earth. If anyone is to solve this problem, one hell of a Hail Mary is needed.
Here is our hero and his ship, the Hail Mary. Full of Dr. Grace.
Weir likes solid science in his science fiction. He uses a couple of handwaves to get our hero into deep space. The major handwave is energy to mass ratios of fuel. Aside from that, I'm sure he took a couple of liberties with biology, but each choice was a smart, calculated one. In this novel, Grace and science are the heroes jointly.
Weir uses Grace's memory loss as a convenient way to place him where he needs to be and then uses the resulting recovery of memory as excellently timed data dumps for the reader. It is used to great effect to expand the stage of the Hail Mary to a greater cast of characters than just Dr. Grace. The reader moves from the present to the past in a delicate dance of memory vs. discovery where Dr. Grace is first introduced to the world end cataclysm that he must prevent.
And damn, some of these characters are excellent. Even magnificent. Eva Stratt is the quarterback of Earth's defenses. She is assigned the task of clearing the way for Project Hail Mary's success. Since success is not assured, Stratt operates on the principle that anything short of total annihilation is a path to success. Including a suicide mission to Tau Ceti to find out why this Earthly neighbor isn't dimming when all of the other stars are. And boy, is she a bastard.
Many of the other characters are charming and likable, even when not compared to Stratt. But none are entirely squeaky clean. Weir builds a cast of believable characters, with very few unnecessary bit characters to muck up the works. Some of the characters are particularly odd, given that they want to go on a suicide mission. And some of that oddly is pretty shocking. But not terrible, in context.
Dr. Grace encounters both wonders and surprises unimagined by the builders of the Hail Mary and each is used to excellent advantage to progress the story.
As a plot device, all of the science onboard the Hail Mary is off the shelf, except for the technology to place the crew in a coma long enough to survive the trip. That is the one point of failure on the mission. If the crew never emerges from the coma, the mission is a failure. Having no other option, that is deemed an acceptable risk.
However, there is a sneaky backdoor point of technology failure introduced by the plot. First, none of the technology at Grace's disposal is any smarter than a laptop or more sophisticated than a college chemistry lab. Dr. Grace isn't an astronaut. He doesn't do checklists or planning because he isn't trained to do so. And pays for it constantly. There is nothing there to warn him of the errors of his ways.
While this would normally be a plot hole, the fact that Grace pays for his erratic and Rocky behavior every time builds tension and drama, all the way to the climax of the story. And it's a hell of an ending, which parallels Mark Waverly's transition from astronaut to teacher in the Martian.
While Project Hail Mary is a very different read from the Martian, the sense pedigree is there.
I am slightly annoyed that I paid full price for this book at Barnes and Nobles, but it was a much needed date night. You can pick the hardcover at a good price at Amazon. This is the portion of the post where you click the link which goes to Amazon and I get compensated if you buy. #Ad
Or you can do what I did for Artemis and grab the Audible version.
