Book #3: The Wrong Billionaire's Bed

The Billionaire Boys Club is a secret society of six men who have vowed success—at any cost. Not all of them are old money, but all of them are incredibly wealthy. They're just not always as successful when it comes to love...
Audrey Petty's always been the responsible one. The good twin.? Successful, dependable, and trustworthy—that's Audrey. She'd be the perfect girlfriend for her childhood crush, billionaire Cade Archer...except that she's pretty sure she's not even on his radar. But when fate (and her chaotic twin) come together, Audrey finds out that she'll be spending the next month with Cade at his remote cabin retreat. It's a dream come true...
Until she meets her worst nightmare.
Billionaire playboy Reese Durham is used to seducing women to get what he wants. But when stiff, too-proper Audrey bursts into the private mountain lodge and scares his companion out the door, it's time for a little revenge. It's clear that Audrey's in love with his buddy, Cade...and it's clear to Reese that blackmailing Audrey with this information can get her to agree to just about anything. Like furtive kisses in the dark, or a secret rendezvous in the woods. Audrey may think she knows what she wants, but Reese is determined to show her what she needs.
And as Reese discovers the volatile minx behind the buttoned-up exterior, he starts to think maybe she's just what he needs, too.

Book #4: Once upon a Billionaire

As a member of the royal family in a small European country, Griffin Verdi’s presence is requested at the wedding of the century. The scholarly billionaire feels out of his depth in social situations, so a good assistant is required—especially when dealing with royal etiquette. Unfortunately for Griffin, he’s stuck with Maylee Meriweather, a pretty, charming, and thoroughly unsuitable woman who doesn’t know a thing about high society—but she sure can kiss. Her lack of polish may sink Griffin, because after all, even his money can’t buy class. But through Maylee’s eyes, he’s starting to appreciate the simple things in life—if simple means the most complicated woman he’s ever met. Maylee is everything Griffin isn’t—and everything he wants—if he can let down his guard and step outside his sheltered world…
