Are you still looking for this book..I have purchased this book from Amazon with low price,kindle version. I used this book for my pmp preparation for practicing 1000 questions..its really standard book.
The response I got after contacting PMI via "chat" on their website was:
"That is not a book PMI publishes so unless the PDF is available to purchase through the store, it is not something that we would have on our website"
