Which Cold War book(s) should I use for APUSH?

Test Preparation AP History & Social Sciences

I am taking the AP US History class, and our teacher won’t cover the Cold War Unit in time for the AP Exam.
Therefore, I am looking for good books on the Cold War, that I can self-study outside of class.
What book(s) should I buy?

Anyway, I want to get a 5 on the APUSH exam.
