Sex and the Senile

Suzie Walker is a septuagenarian who has lived in nine states. She has collected stories along the way and has woven them into a rollicking novel about fictional Marge Avery. Marge has entered the dating scene two decades after divorce.
Suzie is mother of four and grandmother of three, all--so far--upstanding citizens, who may now spend time explaining to friends that yes, our mother/grandmother is a shade off the norm.
