I hate to burst anyone's bubble here, but speaking from personal experience, yes, amazon will tell you who the sender is. The situation was a little bit different so I could be wrong for your case--but when my son was born we received a baby gift addressed directly to him, it was shipped from amazon but didn't have a card. I called and amazon and at first said they could only speak to the receipient. I then explained the receipient was two weeks old and couldn't come to the phone. . Amazon then looked up the sender. So just an FYI. Hopefully your therapist likes the book.
