Macroeconomics Books?

[James Vermillion]

I have been taking CLEP tests since my undergrad is not in business and I will be starting some MBA classes soon (needed to take care of some prerequisites). I have taken and passes Macroeconomics, Microeconomics, Financial Accounting and Principles of Management so far. I studied a bit for the macroeconomics since I had little exposure to many of the ideas and became really intrigued by a lot of it. Anybody know of any good books on Macroeconomics? I am sure many of the reads will be dry but there must be some great reads out there. Thanks in advance BP nation!
