His Until Midnight by Reese Ryan

The Texas Cattleman's Club is having a Bachelor Auction. But Tessa Noble's brother ate something dodgy and he's not able to go. So Tessa steps in to take his place. The organizers are ecstatic and give her a makeover to help her get more money.
Her best friend, Ryan Bateman, is astonished to see her up there. He doesn't think of her... that way. But that doesn't mean that he is going to let someone else win the bid. He can win and they can just let the date go. But when a scandal threatens the auction, the people in charge ask Ryan and Tessa to allow a reporter to follow them on their date. So, they have to make it look good. And that's when it all starts to appear as if they only people they've been fooling are themselves.
I heard about this on the Fated Mates Stump Jen and Sarah episode and enjoyed it completely. It is a Harlequin Desire so it is shorter but a fun read anyway.
