Seducing the Billionaire's Brother (Seducing the Billionaire #3)
Marquita Valentine

Connor Montgomery embraces the title of the black sheep of the family, fully enjoying the perks—no expectations, a jet-set lifestyle, and the women who throw themselves at him because of his last name. The only woman who doesn't care about his black sheep title or his last name is Montgomery Industry's sweet and shy librarian. So, when Faith asks him to help her find his father's design book, he jumps at the opportunity to spend time with her, completely prepared to be the one doing the seducing...until his shy librarian turns the tables on him.
But when the truth comes out and Connor learns that Faith was just using him, will he be able to forgive her?
