Query: A book for those who think Robert Jarrow is a lightweight!

Robert Jarrow praises this book! I think that tells you the level of this text. It's Ivy League Ph.D.-school material with inadequate background provided. I guess if you are already a director of research in an investment bank, this book provides a lucid and compact survey of the current state-of-the-art techniques of credit risk modeling. In short, this is a book written for people who already are comfortable with the subject at a very high level.If you are a regular Schmoe like myself (someone comfortable at the Hull or Cuthbertson and Nitzche level) much of this book may zoom over your head. But if you regulary snicker at folks like me as derivatives dilatants and poseurs, I'd say check it out.The book may be great. But for me it was a waste of money.Did I mention that Robert Jarrow likes it?
