It's a nice SUMMARY of the literature available for those who don't have the time to read it all first-hand. Since my primary interest is more towards equity exotics, the book was more than satisfactory for me. I'd say the target audience is non-fixed income exotics traders, quants without much background in fixed income, and academics.

The best article in the book is probably the one written by Das. He's one of my favorite authors and his chapter in this book is no exception.

My main complaint is that many portions of the book INSIST on using econometric models and pricing kernels rather than the DiffEq framework. For that reason, I like Paul Wilmott's presentaion of the math a little better. I find myself constantly referring back to "Derivatives" and translating what the guys in this book are trying to say.

As with most books in the field, it is also very poor at describing the implementation of the models presented.
