The first installment of a sexy series about a modern-day heroine writing historical novels based on her romantic misadventures with the Bad Boy Billionaire. Jane Sparks has accidentally announced her engagement on Facebook—to the infamous Bad Boy Billionaire, Duke Austen. As soon as it's discovered that Jane and Duke barely know each other (one hot kiss at a party does not a relationship make), she'll be completely humiliated. And then Duke does something Jane never expected: He plays along with her charade. With his hard-partying playboy reputation jeopardizing a 150-million-dollar investment deal, Duke realizes an engagement with the sexy but oh-so-proper librarian could be just the thing to repair his reputation. This good girl tempts him to be very wicked … but only with her. It's unprecedented. Inconceivable. Totally alluring. As the unlikely match of librarian and tech entrepreneur set out to convince the world—and the internet—that their love is real, something unexpected happens: They start falling for each other. But Jane is secretly writing a historical romance novel that could expose their carefully constructed romance … unless two perfect strangers are content to be perfectly scandalous together.
