This is a good edition of the Federalist Papers, the introduction by Gary Wills is excellent. However, I would strongly recommend purchasing the Mentor edition, as that edition contains the text of the Constitution, as does this edition, but the Mentor edition has cross-references to specific portions of the Federalist Papers which address that clause of the Constitution.
In general the Federalist Papers is a must read, no matter what edition you use, for anyone interested in the founding of the US, or desiring to learn how our system of federalism, and separation of powers was intended to work. I recommend reading numbers 10, 49, and 78 first.
