Bidding on Her Orc Boss by Evangeline Priest

Zana Estrada has been living her best introverted life.

As a number cruncher for one of the elite orc families in Obsidian City, she works remotely from her cushy apartment two hours away and gets compensated well for it. So long as she continues to provide the data analysis to keep Clan Urkroz profitable, her manager keeps her as far away from social interactions as possible.
Things couldn’t be better until one day she opens an email with the phrase she dreads the most: All remote workers are required to check into the office. No amount of pleading with her supervisor can get her out of this show and tell. Worse, she is supposed to network with her sales manager counterpart, the luddite XSonagh18…

…who ends up being her boss…
…on whom she accidentally bid in a silent auction…
…and, with whom she accidentally-on-purpose spent a deliciously decadent one-night stand.

Before she can even think of filing transfer paperwork, the big, bad orc boss insists that he needs to honor their date and gives her an offer impossible to refuse.
