A friend, Blair Howard (he writes mysteries, mostly; google the name) did the covers for most of the New Frontiers Series, and he left off the information about where the books occur in the series.
In order, they're The Ship, which is here on SOL, then NFI: New Frontiers Inc, NEO: Near Earth Objects, BEMs: Bug Eyed Monsters, MARS: the Martian Republic of Sol, all of which are available now from Bookapy. Which, as most of you know, is part of the SOL group of outlets for writers.
Still to come: Pirates, which I expect to post to Bookapy today or tomorrow, and Terra, which will take another week for me to revise and edit. It will be on Bookapy too.
The final book in the series, Hybrids, is half-written. My mental issues resulted in writer's block, so I put it away for a while and tried to regain my operating vocabulary. I hope that all the revising has done that, and since the plot is complete in concept, I intend to try to finish the book. If/when I do, it will go on Bookapy too.
And now, back to reading the latest installations on SOL!
