Good Idea!
I was helping a couple of women wrap gifts tonight for children. These gifts were books. What was unique about the books is that they each had a personalized recording of the book that was read to them by a loved one. It's kind of like listening to audiobooks except that the person reading the story is your own grandmother, mother, etc.
Neat idea! I'm sure these books will become treasured momentos after the giver has passed on. I believe that there are books on the market where you can record your own voice telling the story but I can't think of who at this moment.
