The book in three sentences:

• A scientist wakes up from a coma in space with no memory and discovers he is on a mission to save humanity from an alien microbe.

• He must team up with a spider-like alien to repair his ship and find a way to defeat the microbe before it reaches Earth.

• Along the way, he learns more about himself, the universe, and the importance of hope.

Astrophage is a solar dimming organism that absorbs the energy of stars, causing them to dim and eventually die. It is believed to have originated in the 40 Eridani solar system, and it is rapidly spreading through the galaxy. If it reaches Earth, it will be the end of humanity.

Grace's mission was to collect a sample of Astrophage from the atmosphere of Tau Ceti e, a planet in the Tau Ceti solar system, and bring it back to Earth so that scientists could develop a way to stop it. He was successful in collecting the sample, but on his return journey, his ship was damaged and he was put into a coma.

When Grace wakes up, he has no memory of who he is or what his mission was. He also finds that he is not alone on his ship. There is also a small, spider-like alien creature on board, which Grace names Rocky. Rocky is the only surviving member of his crew, and he is also infected with Astrophage.

Grace and Rocky work together to repair the ship and continue on their mission to Earth. Along the way, they learn more about each other and about Astrophage. They also discover that Astrophage has a natural predator, a single-celled organism called Taumoeba.

Grace and Rocky eventually reach Earth, and they are able to deliver the Astrophage sample to scientists. The scientists develop a way to mass-produce Taumoeba, and they use them to eradicate Astrophage from the Earth's atmosphere.
