I spent six years in this world. I fought and I nearly died, more than once. I had friends, most of whom died but some of whom I saved. I met a woman who was achingly like the one I shared my life with on Earth, but who was nevertheless entirely her own person. I defended the Colonial Union, and in doing so I believed I was keeping humanity alive in the universe.

At the end of it the Colonial Defense Forces took the part of me that had always been me and stuffed it into a third and final body. This body was young, but not nearly as quick and strong. It was, after all, only human. But this body would not be asked to fight and die. I missed being as strong as a cartoon superhero. I didn't miss every alien creature I met trying very hard to kill me. It was a fair trade.

The next world is likely unknown to you. Stand again on Earth, our old home, where billions still live and dream of the stars. Look up in the sky, at the constellation Lynx, hard by Ursa Major.

There's a star there, yellow like our sun, with six major planets. The third one, appropriately enough, is a counterfeit of Earth: 96 percent of its circumference, but with a slightly larger iron core, so it has 101 percent of its mass (you don't notice that 1 percent much). Two moons: one two-thirds the size of Earth's moon, but closer than Luna, so in the sky it takes up the same amount of real estate. The second moon, a captured asteroid, is much smaller and closer in. It's in an unstable orbit; eventually it will tumble and fall into the planet below. Best estimate is this will happen in about a quarter of a million years. The natives are not terribly concerned at the moment.
