The Enforcer and His Heart by Kiki Clark

With Keegan’s safety on the line, there is nothing Nico won’t do to protect him.
The mysterious Keegan has been haunting Nico’s dreams.
Ever since the night he stormed through the pack’s protections like they were nothing, Nico hasn’t been able to forget the powerful young witch. Not his scarred face, his loyalty, or his fierce but sad eyes.
Nico just wished he’d caught Keegan’s scent. He ached to know if his fated mate is a witch stuck on the other side of the country.
No one will stop him from finding out.
The Kincaid Pack is trouble.
Everyone knew that, and Keegan’s coven forbid contact with them.
But Keegan broke the rules, and now he can’t stop dreaming about a shifter he barely caught a glimpse of the night he’d helped the pack. The teasing smile he sees every time he shuts his eyes is becoming a near obsession.
One he isn’t sure he wants to stop.
