Book Review: Project Hail Mary

I’m a big fan of The Martian. I enjoyed Artemis. But I was blown away by Project Hail Mary. I went in knowing nothing about it—I didn’t even read the blurb. And I think that was the right thing to do. The plot was unveiled like a true mystery adventure. If anyone wants the same experience as me, stop reading here, and just take my word for it that it’s worth your time!

Andy Weir’s latest sci-fi novel opens with our protagonist waking up with complete amnesia aboard a spaceship. Safe to say, amnesia has been done (All My Circuits, anyone?). But the way Weir uses the memory loss to gradually reveal both the present crisis and the backstory is excellent. The pacing was just right, and all the pieces of the puzzle, from why humanity is facing extinction, how our narrator ended up alone in space, what his actual mission is, all slowly click into place alongside his returning memories.

What absolutely sold me on this book, though, is Rocky. Creating a compelling alien character is incredibly difficult (how many different alien species have sci-fi writers conjured up?). But Weir manages to bring this spider-like creature to life in a way that feels both genuinely alien and deeply relatable. Rocky isn’t just a cool biological concept (though he is that too). He’s impatient, intelligent, funny, and flawed. The sections exploring how they learn to communicate reminded me strongly of Arrival, in a good way. And I loved watching their friendship develop as they worked together against a threat to both their species.

As you might expect, Weir’s protagonist is… very similar to his other protagonists. If I have one criticism, it seems he can only write one main character: the brilliant-but-anxious, funny, slightly neurotic scientist. Luckily for Weir, I like this character! As with The Martian, this kind of character is executed well. His voice is engaging and the he scientific problem-solving is immensely satisfying. (I love that Weir makes me feel like I’m secretly learning while being entertained!)

And in a world of sci-fi where in so many stories first contact means invasion and destruction, Project Hail Mary offers something refreshingly different: the idea that when faced with extinction, different species might choose cooperation over conflict. The plot escalates organically and believably, the challenges build, the emotional complexity is just at the right level… It’s one of those where you know they’re going to get through it, you just don’t know how, or at what cost.
