[Zope] Books?

Im tossing up another zope book. I have "Zope web application construction kit", and frankly, i found that a bit dissapointing in trying to figure out how zope really works. I guess what i need to make friends with is Multiuser database (mySQL) driven websites. So, any comments on, say, "The Book of Zope" and/or "The Zope Bible"?
