A Book For Assistants

Good Morning All!  I hope everyone has had a great week!  I am curious to see if anyone has read a book called KickAss Assistant.  It's the title of the book, I apologize.  I found it on REALTOR.org or whatever and was curious if anyone has read it and it was useful.  I plan to read it shortly, but wondered if I should bother.  I figured if it was on the NAR website, it should be ok for us RE Assistants.  Let me know what you've heard about it, and also if you decide to read it, let us know what you thought about it.  Have a great weekend!  TGIF!
