The Novel that I have the greatest progress with is “A Tale of Two Tigers” which actually is composed of two shorter works, the second a sequel to the first.
“Curse of Wedding Veil Nine” is the first part, which involves the discover of two derelict spacecraft. The setting is in the future at a time when interstellar travel takes place regularly by way of “jump gates”. The tale revolves around an explorer in a seldom travelled star system. I am in the process of rewriting it at the moment.
“Doom of the Bok Globule” is the sequel to “Curse of Wedding Veil Nine“. I am about 1/3 of the way into writing that, but I think that I might not work much on it until “Curse of Wedding Veil Nine” is rewritten. “Doom of the Bok Globule” is set in a different star system. This one has no record of ever being explored.
I think they would qualify as relatively “hard” science fiction with a suspense element thrown in. I’m stepping a little out of my comfort zone in writing the two stories. Others might not think so, but I am not experienced with writing “suspense” stories.
Still it is interesting writing “A Tale of to Tigers.”
