Best books for starting out

[David Parnell]

I suspect that this will set off a fire-storm of disagreement, but I'm interested in what books people have found the most useful when starting out in real estate investing? I'm new to this gig, and have been reading articles, watching YouTube videos, and listening to podcasts. Whilst these have been fascinating, I'm looking for books so that I can go into that next layer of detail. 

I don't mind if you recommend a book that covers all facets of real estate investing, or even something quite specific (what's the best book about tax for real estate investing, deal analysis, legal structuring, etc, etc). I don't mind if its more on the "motivational" side or technical. Anything you've got!
