Rebellion by Loki Renard

Authority Rule #1: Never Cross A Kitari Warrior
Jerri’s life would be a lot easier if she could learn to follow the rules.
It’s not just that Kitari are the most brutal, warlike, terrifying species in the Authority Alliance, it’s that the one she just sassed is her immediate superior.
Commander Atlas thinks Ensign Jerri Tessil is unruly, unprofessional and rebellious.
He’s right.
And he’s the first officer aboard the Audacity to discipline her.
She wants to hate him.
But there’s something about a big, grumpy, growly, mean alien boss that makes her melt.
The Alliance specifically forbids relationships between superiors and subordinates.
But she can’t stay away.
And he can’t resist her.
When the Authority discovers their relationship and forces them apart, Jerri shows them the true meaning of rebellion.
