Us Dark Few by Alexis Patton (Author)

Khalani is a Prisoner
Takeshi is a Guard
Both are bound to the Underground

Khalani Kanes has never stood on the surface of the Earth. Humans have lived underground for hundreds of years, and she’s never left the dark city of Apollo. She longed to visit Genesis, the final place where humanity lives beneath the sun. But when Khalani is thrown into prison for a crime she didn’t commit, all the fragile hopes she once had are destroyed.

In Braderhelm Prison, every second is a battle to survive. Her neighbors are murderers, and the cold-blooded guards punish without mercy. She thought violent inmates posed the greatest threat, but then she meets Takeshi Steele, the infamous Captain who runs her cell block. As cold as he is ruthless, he’ll break Khalani before letting her escape to the surface—a feat no prisoner has ever achieved.
