Quelgheny Series by Gloria Harchar

The faeries' mission -- were Allegro and Largo to accept it -- was to do the impossible: make the earl of Falconwood, "the Black Falcon," fall in love with Phaidra Moore, the incorrigible spinster of Nottingham. Never mind that getting Kain and Phaidra to marry was a feat in itself. Never mind that the woman was a hoyden who made the most atrocious hats and colored them with her own creations, the famous Nottingham Blue... moreThe faeries' mission -- were Allegro and Largo to accept it -- was to do the impossible: make the earl of Falconwood, "the Black Falcon," fall in love with Phaidra Moore, the incorrigible spinster of Nottingham. Never mind that getting Kain and Phaidra to marry was a feat in itself. Never mind that the woman was a hoyden who made the most atrocious hats and colored them with her own creations, the famous Nottingham Blue. And certainly forget that the earl was atoning for his brother's death, keeping himself at the fringes of the ton. Allegro and Largo had to make the twosome fall in love! But the Maestro wanted it so, and thus the skinny faerie and the fat one made up their minds -- very soon both Phaidra and Kain would be ... Kissed By Magic. less

It was another crazy mission. Allegro and Largo thought they'd seen the toughest test that two semi-competent, always bickering fairies from the magical, musical kingdom of Quelgheny could see, but again they were being asked the impossible... moreIt was another crazy mission. Allegro and Largo thought they'd seen the toughest test that two semi-competent, always bickering fairies from the magical, musical kingdom of Quelgheny could see, but again they were being asked the impossible. Get the Duke of Chillhart, Grant Hale, to fall in love with the daughter of a criminal? Why, even if she was better than her thieving sire, even if she had fit herself into Regency society, Lauren Miller's father had incited Grant's father to kill himself! She smelled of wildflowers and her features were winsome, but would Grant see Lauren had the inner beauty to match? For these two humans to find harmony, they'd have to be . . . Enchanted by Magic. Luckily, Allegro and Largo knew just the trick. less

Pixies Allegro and Largo, while trying to make Nolan Monroe, a tormented Earl, and Tessa Ballard, a spy for the British crown, fall in love, must find the shape-shifting heir of Shederin before the power of human love is dimished and the world of Jubilant is destroyed. Original.
