We Don't Start Fights: Theseus Protocol by A. Stargazer

He just wanted to see the stars - not end a war. When a routine diplomatic mission turns sour, the Theseus is forced to play peacemaker in a genocidal conflict. Nathan Sawyer is one of the only humans on board the ship, reluctantly taking command when the captain betrays the mission. Nathan and his team of uplifted misfits must work together to solve a humanitarian crisis on a scale nobody has ever faced. If they succeed, then a lasting peace may spread across the galaxy. Should they fail, then the planet Horthus will be destroyed. Nathan might be in charge, but he has no clue what he's doing. He needs to quickly learn to navigate a labyrinth of intrigue and red tape - and if that wasn't bad enough? One side is eating the other.

To Flail Against Infinity (The Stargazer's War #1) by J.P. Valentine

SPSFC 2023

Infinite power, infinite danger. Growing up mortal, I only knew a few things about cultivators. They like their hierarchies, they hate disrespect, and if you leave one out in deep space long enough, they'll go homicidally insane. It turns out, there's a reason for that. Away from all the gravity wells and biospheres that generate natural energy, things get just quiet enough to notice the infinite ocean of qi entirely incompatible with our own. I should know. I've seen it. Only difference is, I didn't go mad. I wasn't a cultivator. Technically, I wasn't even alive. But now I can sense it. I can touch it. I can cultivate it. From the bestselling author of This Trilogy is Broken! and Dungeon Devotee comes the cultivation epic you've been waiting for.
