Tainted Blood by Carina Blake

The hatred Ian MacNamara’s father felt for him was a lifelong experience; however, Ian’s disrespect for the elder man rendered this hatred meaningless. Eventually, their differences drove them apart. His mother’s death only intensified his hatred of his father.

There was no way to fix this. He wouldn’t even be certain that seeing his father six feet under would do the job. Ian encountered fate in the form of a beautiful and rebellious med student, a reunion as surprising as it was unforgettable. Callie’s perfection was evident to him, a reminder of their passionate night weeks prior.

She was dangerous, and yet also too innocent.

Callie was too good for a man like him, with more demons and enemies than he could count. No, his blood was tainted, and he couldn’t ruin something so precious. He needed to keep her far away from him. “Run,” he whispered—the only chance he’d give her.

Ian was certain of two things: his father needed to be six feet below ground, and she needed to run before Ian didn’t let her escape.
