I have it, but I haven't read it yet. I bought it and Secrets and Lies as part of a 'buy these books together' thing on Amazon, and am reading Secrets and Lies at the mo.
Having had a flick through the first chapter of Beyond Fear I would say that it's more of an intro to the book and seems to make a big deal of how we look at certain aspects of security, which I would guess will be expanded on through the book.
I would persevere with it. Whilst I don't always agree with what he says, Schneiers writing is generally very good and often gets you to think about security issues from a different perspective using examples that aren't neccessarily computer related.
Let us know what you think of the whole thing if you finish it.
