This paperback volume includes chapters 1 through 9 of Fisher's American Constitutional Law, Seventh Edition plus the concluding chapter, "Efforts to Curb the Court."
This was one of the assigned texts for my Constitutional Law: Structure of Government course. I ended up holding onto it after the semester ended and was able to refer back to it plenty when I took Constitutional Law: Civil Liberties. It's a bit dry, but a good primer. Between this and the OYEZ website, you should be able to ace an introductory/undergraduate con law course.
