Omega Hunted by Linsey Moon

The moonlight filters through the trees—the time for the hunt has arrived…

When Savannah Allen’s secret is revealed, her entire life is irrevocably changed. As an omega, she is supposed to be under the control of the government with her every movement orchestrated but her parents had been keeping her hidden until one day, someone discovers her secret.
After being drugged and brought to a mysterious estate in the middle of nowhere she discovers, along with a group of fellow omegas, that they are in the fight for their lives. Being hunted by a group of alphas hellbent on claiming them as mates should be more than enough to contend with.

But when she discovers that more than one alpha makes her blood sing with desire… the stakes have never been higher.
