JavaFX is a constantly changing thing, but appears to have been mostly standardized by Oracle releasing most of it as open source (and the rest to follow very shortly), and JavaFX becoming part of the standard JRE in Java8.

I've been trying to learn JavaFX and so far I like what I see, however I'm having a tough time finding a good book I can curl up with for some good ol' bedtime reading. The Oracle documentation is fine for starters, but I'd like something comparable to the Swing Hacks book or other of the great Swing books. It's important the book is reletively up to date as from my understanding, JavaFX 1.0 is a completely different product than 2.0, and 2.2 has a bunch of new features, etc.

Can anyone recommend some good current JavaFX books or materials to learn this beast in depth?
