I just watched the latest BBC version of Sense and Sensibility with my 7 year old daughter while we (meaning I; she did gymnastics on the couch) folded laundry. She asked a few questions along the way and made sure she was caught up with things between the three episodes. When it ended and the final credits rolled, she asked, "Is it over?"
"Yes, it is."
"Oh wow. I feel so... happy." She bounced from the couch and into my lap and gave me a big squeeze.
And that is how I want to make my readers feel when they finish my books.
