Jill and Derick Dillard open up to ET's Deidre Behar about their new memoir, 'Counting the Cost.' Best known to fans of '19 Kids and Counting' as Jill Duggar, the former reality star explains where she stands today with her parents, Jim Bob and Michelle Duggar, following years of scandals and personal revelations from the famous family. Among those sensitive topics is Josh Duggar, who the family previously confirmed had inappropriately touched Jill, three other siblings and a babysitter. She calls writing about her brother, as well as details about the abuse surfacing in the media, the 'hardest' part of the book process. 'Counting the Cost' is on bookshelves now.
