Good book?

What would be a good book for someone who is looking to switch over to the investment industry and just wants a good book that teaches general knowledge about the industry as a whole. I am not wanting a book that is specific on a certain area, more just one that gives me a good “big picture” of everything and how the whole process works. Thanks in advance for any help!

The Vault online has a guide to asset management careers.

It doesnt even have to be about careers, I am more just looking for something that gives a good outlook on the entire investment industry.

I liked Hedgehogging.
