D.C. philanthropist Sloane Chase and Senator Whit Montgomery are ready to settle down. Sloane is also preparing for a hip replacement - the latest reminder of the lupus she's managed since her twenties. They decide that hiring a home health aide will give Sloane the support she needs postsurgery. Seemingly a godsend, Athena tends to Sloane and even helps her run her charitable foundation. But Sloane becomes sicker, and her uncertainty turns to paranoia as she begins to suspect the worst. Why is Athena asking her so many questions about her foundation - as well as about her past? And could Sloane be imagining the sultry looks between Athena and her new husband?
