This is a great book for any age. I first read it as a teenager, and felt it was so applicable then. In this story, the characters use dots to mark people they don't like, and those with many dots feel like they are defined by their dots. Eventually, their maker shows them how to make the dots fall off, so they don't stick, by not caring what the others think. No matter your age, I think we all need a reminder that we shouldn't let others define how we feel about ourselves, because ultimately what our Maker thinks is more important.
