The Popularity Papers: Book Four: The Rocky Road Trip of Lydia Goldblatt & Julie Graham-ChangHardcover, 1 April 2012

It's summertime, and Julie and Lydia are going on a road trip! After all the ups and downs of their first year in junior high, they're looking forward to seeing the sights and getting some new perspective on their quest for popularity. Papa Dad and Daddy will provide the transportation, and they'll provide the entertainment.
At first Julie and Lydia use their Powers of Observation to catalog the traditions and oddities of each new location they visit, but soon their attention turns to parents and family and negotiating sensitive family dynamics. By the time the duo hits familiar streets again, they may have to accept some uncomfortable truths, but their journey is infused with the humor, heart, and truthfulness that Amy Ignatow is known for.
