Cooper. The Manning Dragons, #1

Cooper Manning and his five brothers were true dragons. Centuries ago, when the humans had turned on their kind, their father sacrificed himself to save his sons by casting a powerful spell which allowed them to walk among the humans. Even centuries later, Cooper couldn't seem to let go of the past and despised most humans. Carson Langley was exhausted. After being forced to work thirty-six hours straight, she unwittingly complained to the new plant owner, now she knew she was fired.
There was nothing left to do but go home and cry about it later. Cooper was sent by his brother to retrieve the helpful woman and bring her back to the plant, and he wasn't happy about it either. It didn't help that when she answered the door she shared his sour mood, and when he touched her hand, the magic that surged between them meant only one thing-she was his other half, and she was human....
Cooper was seeing red.
