Omega Freed by Lyonne Riley

An omega imprisoned for what she is. A kind man who rescues her, never suspecting the truth.

Selene was kept in a locked, dark room for years, hidden by her father to keep her safe from dangerous alphas. Until the day she’s forced to find a way out, leaving her life of captivity behind.
When Harry finds a woman running through the woods, lost and confused, he takes her home to nurse her back to health. Little does he know he’s found a rare, prized omega—one who will desperately need his help when she goes into heat.
But there’s nothing Harry can do to sate her needs, as much as he wishes he could. He’s just a beta.
Or is he?

This is a soft, cozy omegaverse novella about a shy woman with a dark past and the big, cinnamon roll man who wants to help her return to a normal life. It’s a quick and steamy read in a gaslamp fantasy setting, with a sprinkle of thrill and a well-earned happily ever after.
