The Wedding Pact. The Baby Pact Trilogy, #2

After you run away from your parents, hiding so they can't marry you off to some stranger, an organisation that's supposed to help you tells them exactly where you are instead... Gail, an Omega, never wanted to find an Alpha or Beta mate, he assumed that as soon as he mated he would have to give up his freedom, that he would have to obey their every command, become the perfect home-maker that his parents tried to raise him to be.
The only problem, he doesn't want a life like that. Lucien and Cyrus, an Alpha and a Beta, were happy together and never felt the need to take an Omega. An Alpha and a Beta together isn't accepted in shifter society, but they didn't care, they loved each other and weren't going to change who they were just to be 'accepted'. Everything seemed to be going fine, until their worlds collided. Now Gail is pregnant with Lucien and Cyrus' twins, but without an officially recognised mating or a marriage certificate, he can't get health care or even find a new job, both of which he desperately needs.
The organisation that was supposed to help Gail gain his independence from his parents, instead let them know where he was living and now they're doing anything to get him back. Now the trio have to fight against the system to get their mating recognised, to protect Gail, but also their unborn babies. This is the second book in The Baby Pact Trilogy which takes place in an Omegaverse world with shifters and mpreg (male-pregnancy).
This trilogy may include any of these elements: steamy scenes, 'I need tissues NOW' moments, cries of 'why, oh, why' and cliffhangers that make you bite your nails (and curse the author).
