It's always great to see people enjoying a book you made. When my kids tell me that our books are always checked out in their school library, it's a real treat. I hope each child takes something from the book with them as they grow into adults.
And when you see a grown kid (I guess that's an adult!) on the Metro reading a book with your cover design, it's a rush. You'll ask yourself, "Did they chose that book by its cover?" hoping it was a deciding factor.
So when our UK staff received the following letter, it was very sweet. Being a Brit (we moved here when I was four) I was chuffed to see that the Prime Minister would be having a peek.
