If you like hard science fiction, you'll like Altmann
Just like Journey to the Center of the Earth, Merimnae: Inbound reads like a scientific travel journal. William Altmann really went all out on the science, and it's really impressive!
The team of Merimnae: Outbound arrive in the Tau Ceti system and make camp on Physeter. The expedition then really starts with mapping the system and building a new base.
Then, a next ship arrives: Prometheus. It brings the seeds to a human colony and then prepares to reach further into the stars. Mind blowing!
Altmann writes with detailed decication. Hard science fiction at its best.
