St. George, Judith (2007). The Ghost, The White House, and Me. 153 pages. Grades 3-5.
After their mother is elected President of the United States, eleven-year-old KayKay and her sister Annie move into the White House. Although their new home comes with great features, such as a bowling alley and their own chef, the girls miss spending time with their busy mother. KayKay occupies her time by writing mystery books and scaring her sister with stories about a ghost who haunts the Lincoln bedroom. After some persuasion, Annie joins KayKay in investigating the mystery and scaring an important guest, but in the end they get a surprise of their own.
