Omega for Rent by Liam Kingsley

It’s better to fake a relationship than be forced into one… But what happens when the fake relationship starts feeling like everything you never knew you wanted?
Chase Cartwright has a problem—his dad needs him to date the omega son of an important businessman in order to close a deal. But omegas often form intense emotional attachments with alphas and Chase, commitment-phobe, isn’t willing to take that risk. He just needs to figure a way out of it…

Riley Lewis is an omega for hire, and he offers a specialist service—he can take an alpha knot without any of the emotional baggage. And now he’s got a client, a rich alpha who needs him to be a fake boyfriend. But Chase is adamant it’s just business. A fake relationship for show, to keep his father off his back. No sex. Definitely no knotting.
But what’s Chase supposed to do when the immediate connection he feels for the omega turns into a soul-deep craving to be close, too overwhelming to ignore? It’s all-consuming and beyond any kind of human bond, and the alpha will tear apart the world to keep it safe—both Riley, and the new life they’ve created within him.

Because there’s a new danger lurking on the edges of their happiness, another alpha who’s obsessed with Riley, and he forces Chase into an impossible decision: How much is Chase willing to sacrifice to protect the man he loves and the baby he carries?
