"After completing this Quest - I have finished a book in 5 days and I have full understanding"

I am a psychotherapist with a client who puzzled me. I found a book on neurology that might be able to help me but I couldn't get past chapter 1 because I wasn't understanding it. After completed this Quest I have finished the book in 5 days and I have a full understanding, so that I can explain it to others and I have access to resources to help my client to try and avoid her issue occurring again.
