Redemption by KD Jones

Lieutenant Nix Saber has worked hard to earn her position with the Drastan fleet. Her talents have been wasted training warriors, but now she’s finally getting the opportunity to help rebuild Earth’s substructure underground. Not all the humans are happy with her people’s help, but her real problem is with a human male who always seems to get under her skin.
Corey Nash is a survivor. Years in the tunnels after the nuclear disaster taught him that the only person he could really count on was himself. Given the opportunity to train with the Drastan warriors, he jumped at the challenge. Now his people need him to return to the tunnels to help build a city below where they can thrive. If only he didn’t find that bossy Drastan female warrior so distracting.
