Seduced by the Billionaire by Barb Han

Seducing Avery
Avery McAdams believes in order to truly be herself she needs to keep her head down, her guard up, and her focus on her career. When she's hired by sexy, charismatic Ryker Li to pull off the event of the century, a piece of her wants him to see her as attractive, which goes against everything she's convinced herself she believes. Rich, powerful Ryker has made an art form of getting what he wants, when he wants it, and then moving on. But something about Avery makes him want to stick around. Can the billionaire playboy commit to the biggest deal of all? Or will a lifetime of mistrust and suspicion turn them forever into rivals?
The Billionaire Bargain
By choice or by force, everyone eventually walks out of Rae Stevens' life. Wealthy, powerful, and sinfully gorgeous Daegen Tan has it all. Except the one thing he truly wants: Rae, the woman who ended their passionate affair three years ago. He is determined to have her back in his bed. This time, he'll take pleasure in seducing her-and then he'll be the one to leave. Except his heart has other ideas. Can Rae stay long enough to give him a chance? And will Daegen be able to convince her that he isn't going anywhere?
