Alpha Stepbrother (Omegaverse Nonshifter Mpreg MM Romance)

A secret marriage, a secret baby, and a secret mate–will Owen and Caleb ever find out they are meant to be?
Caleb
My stepbrother, Owen, is a beautiful, young omega, and I'm going to make him mine.
I never thought I would find my omega so close to home. When my mother married his father, Owen became my stepbrother. Now his father's scheming is keeping us apart. I won't allow that. Owen is mine. No one will have him but me.
Owen
So much has happened since my father married Caleb's mother. We're stepbrothers, but we're so much more.
My life is so complicated now. A secret marriage and a secret baby don't make it any easier for me to figure out what I feel for this gorgeous, domineering alpha.
Is this real? Could we be fated for each other, or will my father's threat of an arranged marriage keep me apart from my alpha, the man I love?
