Alpha Costello's Fairy Luna

Madeline Yearwood: Twenty two year old Maddie Yearwood has lived almost her whole life knowing that her and her Mother were fairies, and that they've kept this secret all their lives while living in normal society. She's aware of the fact that other creatures besides fairies exist too, but she's never met one of them, and doesn't know much about them. One day a very handsome stranger comes into the art studio, where she's been taking classes. After an odd encounter with him her life starts changing rapidly. With family secrets exposed, and a fated life she never fathomed would be hers, Maddie is nothing except overwhelmed.

Costello Albertine: Alpha of The Sapphire Pack, the strongest and largest Pack in North America, Costello has been a dedicated and respected Alpha since the age of eighteen, and been waiting for the day he'd finally meet his mate. After weeks of trying, when Costello finally finds the time out of his busy schedule to go to an Art Class in the city he never expects to find his absolutely alluring mate sitting there. With a Rogue King who's determined to ruin his life because of an old Grudge with Costello's father and with his mate not being a wolf, and him not being sure she's human either, Costello is about to face nothing but difficulty in his love life.
