As far, so good. John has a very nice way of explaining the language, either for starters or for experienced ColdFusion developers.
The book starts with a general basic view of the ColdFusion functions and then grows in content to the more experienced developer.
I am an expert in ColdFusion 7, with little experience in CF 8. I thnik this book is what I needed to lead me to the CF 9 deal.
Pakt publishing made available a sample chapter for anyone to download. You may find the PDF file here.
