Omega in the Middle by Samantha Cayto

Sold by his sire, Ben is an abused omega forced to sell his body for money. His rescuer comes in the unlikely form of a beta living among humans by choice, and who has no intention of exploiting Ben. Now the beta has brought him to the Rogue Pack for adoption. While Ben is happy to be safely tucked within a protective pack, it means facing his destiny as a breeding shifter.
Daniel loves the life he’s carved out in the human world. He doesn’t want to go back to living in a pack, but recognizes that he has to take care of the vulnerable omega he’s rescued. The plan is to find the mysterious Rogue Pack that he’s heard of, leave Ben in their capable hands, and return to his comfortable life. That was the plan, but something about the fetching Ben is causing him to drag his feet.
Carr is tired of living the life of a feral shifter. He followed his friends without hesitation into the wild, but now he has a chance to become part of a new pack. The arrival of a sweet and available omega gives him a reason for joining the Rogues for good. The only problem is the irritating beta who doesn’t seem inclined to give Carr a clear path to claiming Ben.
With everything he’s endured, Ben isn’t sure about taking a mate. Although he knows he can’t stop his heat, he’s determined to breed first and worry about mating later. Make that never. Except his nature has other ideas. His heat is coming fast and hard, not giving him the time to decide which of the two dominant shifters he wants to breed him.
Daniel, Carr and Ben are three shifters thrown together in a primal dance that’s designed for two. They are going to have to find a way to work together, or risk Ben’s very life.
