The Atlanta Chronicles by William Chester

Paige has only loved one man, her boss and mentor, Robert. At 56, Robert has just found out he is dying of cancer. Standing at the pinnacle of his career, Robert's success in business stands in stark contrast to his failures in his personal life. As Robert spends his remaining precious few months helping his protege, Paige, consolidate control of the firm; he watches as the lives of his children spin out of control.
