We Choose You by Katy Manz

James and Aidan didn’t need fate. They had each other.

Alpha James and Beta Aiden love each other and don’t care what fate has to say about that. Mating doesn’t need to be based on pheromones and scents. And kids? There were many ways to build a family.
When fate comes knocking years later, James does what any wolf in his situation would—he runs away. He has a mate he loves more than anything, and they’re just about to get everything they want: a family. He can’t risk losing everything because Fate decided to be a butt.
Omega Riley scented his fated mate once months earlier, and the wolf ran away. He is coming to terms with his singledom. Everything is going as well as it can, that is, until his fated mate’s children walk into his classroom.
We Choose You is book one in the sweet with knotty heat MM shifter mpreg romance series: Choice Vs. Fate. It features an alpha wolf shifter who mated his beta best friend, the omega sent by fate, true love, twins who will steal your heart, adorable babies, and a guaranteed happy ever after.
