The Investigator by Anna Hackett

It should have been easy. Stay away from her boss’ hot brother.

Museum curator Haven McKinney has sworn off men. All of them. Totally. She’s recently escaped a bad ex and started a new life for herself in San Francisco. She loves her job at the Hutton Museum, likes her new boss, and has made best friends with his feisty sister. Haven’s also desperately trying not to notice their brother: hotshot investigator Rhys Norcross. And she’s really trying not to notice his muscular body, sexy tattoos, and charming smile.
Nope, Rhys is off limits.

Investigator Rhys Norcross is good at finding his targets. After leaving an elite military team, he thrives on his job at his brother’s security firm, Norcross Security. He’s had his eye on smart, sexy Haven for a while, but the pretty curator with her eyes full of secrets is proving far harder to chase down than he anticipated.
Luckily, Rhys never, ever gives up.

When thieves target the museum and steal a multi-million-dollar painting in a daring theft, Haven finds herself right in the middle of a deadly situation. With the painting gone and Haven in danger, Rhys vows to do whatever it takes to keep her safe, and Haven finds herself risking the one thing she was trying so hard to protect—her heart.
