Protective Daddy by Liam Kingsley

He can’t see past his own scars …
After he was left for dead in a wildfire, Ian can’t help his monstrous appearance. No one could love him with his beastly features, not even his own family. Add in the fact that he’s an omega raising a daughter on his own and he’s destined to remain single for good. But when Steve looks at him, there’s a different kind of heat in his eyes, one Ian wants to reach for, if he can guarantee he won’t get burned again.
He’s not strong enough for a mate of his own …
Detective Steve Daniels may be an alpha, but he’s not nearly as strong as the other members of his pack. He’ll never be alpha enough to claim a mate of his own. But Ian’s scent drives him crazy, and spending time holed up with the man and his daughter makes Steve wonder if he might be just the mate Ian needs to heal and grow.
The wolves can’t make it work as long as Ian stubbornly refuses to perceive his own worth. Steve sees the man, not the scars, and he’ll do anything to prove that his mate is worthy of love. He’ll have to find inner strength of his own to claim his omega and protect their growing family, and this time Steve will be worthy enough to love everything he holds dear.
