Disgraced noblewoman Evanora Harkness will do anything to get back into the aristocratic crowd, so she has no issue sending her daughter Agatha into the lion’s den to act as Rio’s newest lady’s maid… as well as her eyes and ears.
But Agatha has other plans.

Summary
“No, but it’s not only the work,” she continued. “It’s you. I don’t appreciate you singularly as my assistant, I appreciate you for you.”
Her assistant’s breath hitched; when she exhaled, it fanned across Rio’s cheeks. “Are you sweet talking me for business or pleasure?”
Rio’s scent suppressants had to have been struggling, everything inside of her felt gooey and warm, and her scent was definitely reflecting it. When Agatha’s nose twitched, Rio pulled back, clearing her throat. “Sorry, it’s late. I’m tired.”
Agatha’s face fell, but she didn’t say anything about Rio attacking her with pheromones. Hell, Agatha most likely couldn’t smell them anyway. “Yeah.” She stood, shucking her skirt down and sliding on her heels. “You should get home to Wanda before she starts worrying about you, or something.”
Or thinking Rio was banging her assistant. “Yeah.”
OR
Engaged CEO Rio harbors an unrequited crush on her assistant, Agatha. Between wedding planning, concealing her true designation, and running a company, Rio has several reasons to stay away...yet she never does.
OR OR
It's more horny omegaverse!

Summary
Massachusetts, 1743. Agatha hears rumors spreading around New England that her evil mother sold her in an arranged marriage to Lady Death at birth. She and Rio are only courting, but she decides to scam the entire New England witch population into believing that she is betrothed, and then married, to Lady Death.
And if she lies a little bit to embellish the stories? If she maybe, perhaps, fakes a pregnancy? It’s not as if Rio is ever going to hear the rumors and fall for the scam herself. No harm, no foul.
Right?
