I am not familiar with the book you are discussing.

Cathy Anne Murtha is a very well regarded instructor. I did a search of her web site for Internet Explorer and here is a link to the results.

It appears she only has material for the Internet using JAWS but browsing will be almost identical.
Since I don't know what you want to learn, you might wish to contact her and ask if the book deals with the topics you want to learn.

Also, since I don't know what you want to learn, I don't know if a book is the best way to proceed. You might be able to learn what you want by asking questions here or on the chat list, whichever is appropriate for what you want to learn. Or one or two hours of personal instruction might be a good approach.

If you give us an idea of what you want to learn, you may get better help for your specific needs.
