I am writing to your previous letter about the
iPhone. I guess everyone really wants to have one as it is very convenient. You
may do a lot using an iPhone but on the other hand it is extremely expensive
especially for a teen. Not everyone can afford it that’s why everyone wants it.
As for the book you are asking about, I can say
that there is a wide choice in any e-library where you can easily download it
from. I’ll send you one of the references. There is a list of classical and
modern e-books. You’ll see yourself which one to take.
