Right Girl, Wrong Alpha by DJ Bryce

As Chief of his Clan, Logan is surrounded by friends and family, the only thing missing is his mate. Natasha has always known that she was raised to be the mate of an Alpha, but being in her sister’s shadow has enabled her not to worry about it too much.
When Logan comes down to help the pack, he knows instantly that Natasha is the one for him. When she is put in harms way, he will stop at nothing to save her. Natasha never imagined that her mate would be anything other than a wolf, but although her feelings for Logan take her off guard, she can do nothing but succumb to them.
