Shades of Winter by E.M. Lindsey

The first time Dante saw Liam, he was in the club.
All leather.
And mesh.
And willing.
The second time Dante saw Liam, he was a client.
All cold.
And quiet.
And in danger.
Dante is nothing if not professional when it comes to his job as a bodyguard, but being hired on to protect the young cellist he’d once met in a dingy bathroom wasn’t high on his list of things to do for the holidays. Especially knowing that Dante can no longer touch him.
And it doesn’t help that Liam starts pushing every single one of his buttons after they find themselves snowbound with Liam’s stalker hot on their tail. Dante needs to find a way to draw a line between them, because he’s not willing to give up his career to have Liam in his bed. But he also knows he can’t ignore the one thing he’s figured out:
Liam needs a firm hand, and Dante knows how to give that to him.
At some point, Dante will have to make a choice between duty and pleasure, but he’s starting to wonder if that risk might not be worth everything.
