Students of Presidential history know that the White House has been home to various animals, pets of the residents, and the scene of more than one set of hijinks. In fact, there is a tradition of playing pranks on some of the newcomers to the residence. It's nice to have a book in which the outgoing and incoming President are groundbreakers: President Lopez is Latinx, and President-elect Williams is an African-American female. Middle graders Ingrid and Winnie Lopez are the current First Daughters, and while they want to make the incoming First Daughters, Skylar and Zora Williams feel at home, the prank war they start quickly gets out of hand. Ingrid is finding it hard to leave all that is familiar behind as the First Family gets ready to move to California while Winnie looks forward to the relative freedom of the changes in their life. Although it would never happen--for security reasons--both families live together in the White House in the weeks leading to the Inauguration. As the stakes are raised in the prank war, the girls take all sorts of risks and cause plenty of problems for the staff and themselves. While many middle graders will enjoy this one because of those pranks, it was hard for me not to disapprove and worry about what might have gone wrong. Not only did the pranks seem mean-spirited rather than funny, but they could have endangered lives and distracted the Secret Service. The book does contain some neat insider points about living in the White House, and the escape of Laffy, the ferret, provides amusement, but it was hard for me to get over the meanness of the pranks. Even the farewell letter written by Winnie and Ingrid didn't save this for me. And perhaps it's a small matter, but the end of chapter 19, page 236 has an exchange between the twins after the other girls have vacated the premises. Skylar and Zora are talking about their new roles and celebrating, and all of a sudden Ingrid's name pops up as one of the speakers when clearly it should be Zora. Ingrid's no longer in the picture or in the White House. Still, despite my concerns, this one will find a receptive audience.
