I think this is the first bit of hard science fiction I've published. I wrote it with younger readers in mind -- the main character is thirteen -- and it's the kind of thing I would have wanted to read as a kid.
I loved (and still love) board games and PBS NOVA as a kid, and both of those things came into play for this story. Many games of High Frontier got me thinking hard about different asteroid mining possibilities. And Emergency Mine Rescue from NOVA gave me some engineering insights into digging deep. NOVA also has a great resources for learning about space.
