When the White House was Ours by Porter Shreve.
I really enjoyed this book. Set in Washington D.C. while Carter was in office, it's the story of a family who tries to open an "alternative school", while manly focusing on the 13 year old son who's trying to find his place in his family and the world.
Misfit child in the 70's? I can relate! Though Carter is actually the first president I remember being aware of. Every little girl wished she was Amy Carter.
