Elizabeth Lennox

Autumn hates it every time some beautiful women walks through the doors of The Thorpe Group because she knows that the woman is Xander’s latest fling. She refuses to let Xander get to her, hating him for his philandering ways. She tries to initiate an office truce, but the dratted man just keeps on bringing his lady loves into the office! In her mind, it is unprofessional and she’s not afraid to confront him!
But what happens when their true feelings for each other break through their fighting?
