Macroeconomics is a rapidly changing field. To get a sense of the geography, you might find it useful to read two surveys (which are already on the verge of obsolescence…):
Blanchard, O. "What Do We Know About Macroeconomics that Fisher and Wicksell Did Not?" Quarterly Journal of Economics 115, no. 4 (November 2000): 1375-1410.
Woodford, M. "Revolution and Evolution in Twentieth-Century Macroeconomics." Paper presented at Frontiers of the Mind in the Twenty-First Century, U.S. Library of Congress, Washington, DC, June 1999.
For two more recent and more polemical, pieces, you may also want to read:
