I technically haven't read the book, but I listened to the audiobook and absolutely loved it. Frank Muller was the narrator and he has a way of making the characters come alive. I'd recommend at least trying the audiobook, if you don't think you can stand reading the book again.
I can understand a 13-14 year old not enjoying the book, but I think an older and therefore (hopefully) more patient and mature reader would be able to enjoy it. You might be able to identify with the older Pip a little more now.
