The Revenge of the Radioactive Lady by Elizabeth Stuckey-French

Marylou Ahearn has finally tracked down Dr. Wilson Spriggs. More than fifty years ago, he gave Marylou a radioactive cocktail while she was pregnant. Marylou's daughter then died at age 8 and she's blamed Spriggs ever since. Finding him in Tallahassee living with his daughter Caroline, her husband Vic and their three teenagers (Otis, Ava, and Suzi), Marylou masquerades as their new neighbor Nancy Archer. Vowing to murder Wilson, Marylou involves herself in the family's lives--including their eccentricities and unhappiness --and finds things might not turn out as she expected. The Revenge of the Radioactive Lady is an entertaining, quirky character-centered novel told from the point of view of all the participants. It will be published next month.
