Only two cover sof the brilliant Heechee series. So far...

I'm working on extending this theme to the other books in the series. I abstracted the heechee ships and put them on a slightly alien landscape (look sideways). The rest of the books in the series will get the same ships in different environments, such as deep space and/or a space warp. The same look will of course follow, as it did with the Enders saga below.
