Who says an omega can't save herself?
Adaria's father trained her alongside her brother. When she's kidnapped, she manages to free herself and the other omega trapped with her, but they aren't the last to be taken.

They want her to end it.

Someone is stealing the omegas before they can be sold. Karn is hired to find out who, and stop them.
A mercenary can't be picky about the jobs he takes. When he realizes the culprit he was hired to catch is an omega herself, she shows him not all of them are damsels in distress.

Some can take what they want, even from an alpha.

***This is Book 2 in the Sci-fi Omegaverse series, The Legion Omegas. It can be read as a standalone but is better enjoyed after The Omega Prize.***
