Orbiting a dead world rich with ancient history to find her people,a newly minted female admiral must convince a hard-nosed male security agent of her loyalties and allegiances after being discovered she descends from the bloodline of his people’s eternal enemy, a nearly extinct race of superhuman slavers.

I find this really hard to read and understand.

It’s a doomed expedition. If we know from the outset it’s doomed where’s the story? A doomed expedition launches and fails as expected… because it’s doomed. THE END.

What’s a Supernova Admiral? Is a Supernova a ship? Is it a rank? Don’t add details like this unless you’re sure everyone will understand them.

Why does the fact she’s wary and attentive come into play? Why do we need to know this?

Who is the main antagonist? Pick one and go with that, it’ll be easier for a reader to understand what’s actually going on if you remove the lesser antagonists and focus on who is the one that will give us the stories end.

So her goal is to stop her reputation being tarnished. Why do we care about that? There’s is nothing in this logline that relates to how important her reputation is, and if she’s in any way affiliated with this doomed mission then surely her reputation’s in tatters anyway?

Strip this way way way back and focus on what the protagonist wants… to find her people. Tell us why she’s alone. Why is it important for her to find more of her kin? Tell us how she ended up without her people. This is your story.
