In this sequel to Liberty Porter, First Daughter (2009), nine-year-old Liberty continues to explore her new White House surroundings, copes with her first day at school and takes a field trip to the Smithsonian National American History Museum. Liberty’s efforts to be “nice, friendly, and welcoming to all” are frustrated by a small group of girls who want to monopolize her, and the extra attention she gets is a burden. Sprinkled with trivia about White House life, U.S. history and the museum, this will surely appeal to readers already intrigued by the lives of the current White House children. Who would not want to be part of a class invited to slide on the floors of the East Room and eat ice-cream sundaes with the president? Pooler’s grayscale illustrations break up the text every few pages, as do occasional lists and plentiful dialogue. Events from the first book are mentioned, but readers can easily start here. Those drawn in by the new-at-school story and friendship issues will stay for the fun. (Fiction. 8-11)
