A company called Planetary Resources wants to mine asteroids that are close to Earth for water and precious metals. While Planetary Resources is looking at near-Earth asteroids, NASA has its eye on a bigger prize. The space agency is planning on sending a probe in 2023 to a massive asteroid circling Jupiter that is made almost entirely of iron and nickel.

The Martians were giants with the strength of twenty men. When they attacked Earth, it looked like all was lost. The Martians were just too strong.

The story starts as the war for Earth ends, and humans chase the aliens back to their home on Mars.
