Space Fleet Academy: Year Three
The deadliest lessons aren't taught in class.
Third-year cadets don't just take classes at Space Fleet Academy. They lead them.
Constantine Ramsey and his cohort are assigned to lead a first-year survival course in Earth's most unforgiving wilderness, the first full-immersion program of its kind. No simulations. No instructors watching from a safe distance. Real terrain, real consequences, and a generation of raw recruits who don't yet understand the difference between a mistake and a casualty.
Constantine knows the difference. He learned it the hard way.
But something is wrong in the backcountry. Equipment fails in ways it shouldn't. First-years go missing on routes that should be clean. And when the threat stops looking like an accident, Constantine has to lead cadets who still trust authority against something that has already beaten the people who were supposed to protect them.
Year Three was supposed to be about preparation to become an officer. It turned into a test that no one expected.
The Mandate built the Academy to create leaders who make hard choices. In his third year as a cadet, Constantine is beginning to wonder if the hardest choice is deciding who the real enemy is.
Space Fleet Year Three is the fourth book in the BIOSTELLAR series and continues the military SF series perfect for fans of Ender's Game by Orson Scott Card, Starship Troopers by Robert Heinlein, and The Expanse. The training wheels are gone. Now find out what these cadets are actually made of.

May 19, 2026I loved the story and still think the concept is very interesting. Where this is losing me is with the prose and dialogue, which is largely written by AI. I'm a huge proponent of AI, including for the purposes of writing novels. One day AI will be good enough to write novels on its own, but it is not today. Unless one thoroughly edits an AI-written manuscript to the point that it largely doesn't even resemble the original draft, AI-written prose is mediocre at best, downright unreadable at worst. This novel is far from unreadable, but the overuse of certain phrases, sentence structures, and literary tools made reading this very repetitive and difficult to get through.
