There are numerous books written about parenting but very few about the relationship between parents and their adult children. Mother - Daughter Duo Lisa Scottoline and Francesca Serritella have teamed up to write a series of books with essays from their lives- both living together and apart. The most recent is titled Have a Nice Guilt Trip. Lisa and Francesca join The Point with Mindy Todd on the phone from their homes in Philadelphia and New York.
Here's a link to the Nantucket book festival, in which the author will be participating.
