Knot and Order by Zoe Kassel

David has a secret. He’s an omega lawyer living in an alpha’s world. For year’s he’s taken expensive black market hormones to suppress his heats and cover up his scent. But what choice does he have? If his secret gets out he’ll be fired, and some alpha will swoop in to bend him over and breed him good and proper. All he wants is to do his job, make partner, and keep his secondary gender a secret.
Michael knows that the world is unfair. As an alpha, he has all the advantages in his favor. He does pro-bono work for omega rights, covers up his scent so he doesn’t trigger an omega’s heat, and never goes after what his body craves the most: a male omega. All in all, he does his best to be good in a world where it’s too easy for an alpha to be bad.
But now David and Michael have a case, and the more time they spend together, the more the temptation to see what they’ve been missing grows. If they’re not careful, things could get out of order.
