A man wakes up alone, in a room, groggy and without memories of who he is or why he is there. A medical robot is tending him. It eventually comes to light that he is Dr. Ryland Grace, a high school science who was previously a leading researcher in the field of alien life. Such life was purely speculative until the sun started slowly fading, something that will in time lead to the death of all or most life on Earth.
Grace finds himself deeply involved in Project Hail Mary, a no expense spared global effort to find a solution. Years later, in orbit around a distant star, Grace, finds an ally in his quest. But this ally is not human.
In some ways, it is easy to draw parallels to The Martian. An impossible mission. A snarky and clever protagonist who overcomes difficult challenges. Interesting science problems. But the scope of the story, and the stakes, are both much greater. Project Hail Mary certainly has the same page-turner quality and charming snark as The Martian, making me laugh out loud on multiple occasions. The ending added unexpected gravitas to the story and was a beautiful coda.
The alien is cleverly imagined and imbued with a charming personality despite being so very alien. The fact that the alien’s environment adds to Grace’s challenges doesn’t hurt. How relatively easily communications is established stretches plausibility, but on the other hand, the process is both clever and charming.
