Latest word from WordFire Press is that the formal release date for "Another Girl, Another Planet" is Feb. 1. In view of that, here's the prologue again, to whet your appetite:
There is a small valley ten kilometers from the joint Mars colony, not visible from the surrounding desert, in the heart of the Melas Chasma in the Valles Marineris. As you approach it you will see three crosses—one a traditional Latin cross, and two Celtic crosses.
One of the Celtic crosses is next to the Latin cross. The other Celtic cross sits off to the side. It’s obviously a small graveyard. And you’re the first person to see this lonely place since I was there in 1985.
You want to know what I know about it?
I know everything. I dug those graves. By hand.
Do you want to know why?
Sit down; I’ll tell you.
It's already available via Baen Ebooks. Here's the link.
