Forever Ink - Montgomery Ink, #1.5

To Callie Masters, there's nothing like a man with silver at his temples. When a silver fox walks into her booth, she nearly falls to her knees in appreciation. He's suave with a hard edge, a wolf in a power suit. Her job is to work on the ink on his back, not daydream about something far more tantalizing. Morgan McAllister knows he shouldn't want the woman at his side, and not only because of the age difference.
They come from different worlds, and he refuses to bring such a pure soul into the cutting edge of his circle. Yet the fire between them cannot be doused, and one longing look sends them into each other's arms. Misunderstandings and cutting betrayals are only the start of what stands in their way, and if they aren't careful, they'll lose everything before they even had a chance to truly begin.
