Seconded. Secrets of the Temple by Greider is pretty accessible (if biased, as they all are).

Also, the EconTalk podcasts are awesome: http://www.econtalk.org/archives/money/

E.g.

- David Laidler on Money (http://www.econtalk.org/archives/2013/09/david_laidler_o.htm...)

- Sumner on Money, Business Cycles, and Monetary Policy (http://www.econtalk.org/archives/2013/03/sumner_on_money_1.h...)

- White on Hayek and Money (http://www.econtalk.org/archives/2010/02/larry_white_on.html)

- etc.

I second the EconTalk podcasts. I've been listening to them for over 5 years. They are hour long interviews on a wide variety of subjects. The host, Russ Roberts, does a great job of letting the guest get his or her point across even when you suspect he disagrees. The tone is polite and non-confrontational. It is more about accurately presenting a position than debating, although there is some point/counter-point.

I cannot exaggerate how much I've learned from EconTalk. Plus, there's even an episode with Paul Graham about ycombinator and startups:
