His Wicked Needs by Rochelle Summers

When Amelia finds herself in an upmarket New York hotel bar, drowning her sorrows with shot after shot of vodka, she is unaware that her decision to start drinking on that of all days would lead to an exciting encounter with a handsome stranger.
Just a short time after meeting the man who came to her rescue as she slowly got drunk, she was writhing around in his bed, enjoying every pleasure he could offer her. But in the morning, when she knew it was time to go, she slipped quietly out of his apartment, determined to never see him again.
Until she turned up at City Central Hospital to take up her student residency…
Upon entering the office of Dr Marcus, Amelia finds herself looking into a familiar face and one she thought she would never see again. But her shock at seeing him soon turns to disappointment. He doesn’t seem to care, doesn’t even seem to recognize or remember her and is only interested in her ability as a doctor.
Despite the simmering sexual tensions that continue as Marcus and Amelia start working closely together, they both do their best to keep them under control and maintain a professional exterior at all times.
But how long can it last? How long before Marcus cracks and has to have her again? And how long before Amelia gladly accepts?
