With life being so busy, I deeply regret the fact that I have so little time to enjoy my (paperback) books. I try to look for ebooks but it has been difficult to find something I want/need. Imagine my joy when I found the above book on the Google Play Store. As my smartphone is with me almost all the time, I am able to steal private moments everyday to enjoy this treasure of a book. Thank-you Irving Karchmar! Jazaak Allaahu khayran!
