By Arthur C. Clarke
I read 3001: The Final Odyssey by Arthur C. Clarke. (There are more books like this. They are 2001, 2010, and 2061.) The main problem is that when Frank Poole finds Dave Bowman and HAL 9000, both star children, (a "super" being) tell Frank that the Monolith (a big, black, vertical object, found on the moon, Earth, Jupiter's orbit, and Europa,) is gong to make their sun go supernova, therefore destroying all life on Earth. So Frank gets a very deadly computer virus. From a vault that stores all the computer viruses in the world, and he infects the Monolith. After they infected the Monolith all the Monolith disappear. And Earth is saved.
3001 is a good book. But the beginning is bad because it starts off with people in a spaceship blowing up comets. And the book doesn't tell why they blow up comets, and who they are, 'till later. The middle is good because it tells all about the future, people, and other stuff. So you know what happens when the action starts. The character in the book were okay, only about seven because I don't like a lot of people to keep track of. The ending is okay because it wraps up everything: "Whatever godlike powers and principalities lurked beyond the stars, Poole reminded himself, for ordinary humans only two things were important: Love and Death. His body had not yet aged a hundred years: he still had plenty of time for both."
