Dot.

Randi Zuckerberg's Dot, a picture book about a girl by that same name is delightful - covering a topic my own children need to think about themselves.

Dot knows a lot. She spends most of her time with technology communicating with others and learning lots of stuff. Yet, Dot needs a reminder to spend time outside, to communicate with people face to face and not virtually. 

Young readers will understand the message as will older ones and this is a book that kids of all ages can enjoy. By the end of the story Dot knows even more than when the book began.
