Between IT codes and tingling passion. By day, Fallon writes code for a software company; by night, she writes spicy romances. So that she doesn't have an even harder time among her male colleagues than she already does, she keeps her career as an author a secret and publishes under the pseudonym Rosalie Golden. This makes her all the more hesitant when her publisher suggests she give a reading. And indeed: her rival Jesper, of all people, is standing in front of her. Without further ado, Fallon poses as her fictitious twin sister Rosalie, in whom Jesper takes an unexpected interest. When he is more helpful at work than ever before, Fallon hatches a plan: she will meet Jesper as Rosalie until she gets her long overdue promotion. Or he hacks his way into her heart.
