Day And Night On The Space Station is the second book of the chapter series, Keystone Passage. This time Cliff, Monty, Shandra, Duante, and Quisha visit to their Grandma and Grandpa in Washington, DC. An ordinary family fun fair turns out to be extraordinary when Cliff, Duante, and Quisha find themselves someplace else. They must figure out where they are and whether their surroundings are real or fictitious. Along the way they not only encounter scientific phenomena but learn a few things about the history of African Americans.
