Calling Invisible Women by Jeanne Ray
One morning former journalist and unenthusiastic gardening columnist Clover Hobart finds herself inexplicably invisible. Not just unnoticed, a state familiar to all females over age fifty, but invisible.
What is a gal to do when her husband and son do not even notice that she is gone? After an acceptable period of panic and whining, Clover finds unseen connections, a cause, and courage.
