Frank McCourt has written the Foreword to a new collection of essays (edited by Nell Casey) entitled "An Uncertain Inheritance: Writers on Caring for Family." "There are two great themes in this book: suffering and heroism. You'll be shocked by the honesty in these narratives, the mixed feelings we have when our parents - or family members in general -suddenly become so much of a burden that we have to change our lives," writes McCourt Among the 19 authors who contributed to this at times touching, at times disturbing volume are New York Times writer Sam Lipsyte, Jerome Groopman and Andrew Solomon.
