Dustin. McCullough's Jamboree, #3

Mackenzie's shift at the hospital had just begun when they told her that a patient friend of hers was back in the ER and asking for her. When she entered the curtained room, the last thing she expected was for a McCullough to be sitting next to her patient. It wasn't Hawk, thank god, but the man looked enough like him he could have been his twin. Hawkins McCullough was on her shit list, and if this man was related to him, she didn't want anything to do with him.
It didn't take long for Dustin McCullough to figure out that this feisty doctor was his mate. And when he found out that his brother had hurt her, it took a great deal of strength to keep his cat from killing him. Mackenzie was at her wits end. Random attacks to her person and bullets flying had the entire McCullough family in an uproar. And just when they thought they had everything about under control, Hawkins drops a bombshell that had them all stunned.
Can Mackenzie find it in her heart to forgive Hawk before it's too late?
