An Introduction to Planetary Defense

I find it is a very fun book that nevertheless finds a good balance between rigor, seriousness and sense of humor. It deals with a typical science fiction topic, "What would we do if aliens invaded us," but it does so from what is really feasible.

This captivating read immersed me in the complex world of cosmic defense, the boundaries of space exploration, and modern warfare. After reading it, I realize how unprotected we are.
