Three Handsome Billionaires and a Pretend Fiancée

If there's one thing McKenna Riley is, it's being resourceful. So when she lands a new job as a PA, she firmly believes she's more than capable of handling it-never mind that she's the granddaughter of the housekeeper of her new bosses' mentor.

Piece of cake, and she'll do it all in a pair of heels, embellished just the way she liked it, eclectically.
But also on her to-do list is finding three pretend brides-to-be for each of her three bosses for various reasons for one night at a business/family dinner, and suddenly everything that can go wrong does. What was that about her being resourceful again?
