I read the first two Dig Allen adventures (the “pilot” about a fallen civilization in an asteroid, the other about tiny people living in Mercury’s twilight zone) in grade school. I totally dug these; they are dated space opera by today’s standards, but really blew my 3rd grade mind back in the day. Several scenes are coming to mind as I write this. Like, the folks in the asteroid subsist on a grey oatmeal like substance produced by machines. Or the tiny Mercurians diving behind a sabotaged control panel to rewire it before the heroes’ ship falls into the sun.
I didn’t even know that there were four other books until college, when a friend told me about them. Our campus SF library had a copy of an adventure set on a moon of Jupiter which was in the process of being terraformed.
I wonder what it would cost to get the rights for ebook publication?
