Omega Run. Recycled Souls, #1

Lyra's last conscious thought was being trapped under debris in a dam collapse. When her consciousness woke up, things were... different. She was in her sixth decade, but her body was slight and curvy, and she had a lot of blue hair in lieu of her normal mud brown. That was different. She meets the medical team, and they are aliens with pointy ears. Fair enough. She now has pointy ears as well. A briefing lets her know she is an omega.
She is the only omega on the entire planet and the first of her kind to wake. What follows is a dizzying culture shock, a lot of firsts, and being the target of a mate-drive run that will see her with partners by the end of it. The first Omega Run since the natural omegas died. What could go wrong?
