I taught first grade for decades and there is nothing else like this out there. It's a game changer for children and adults. The book starts in the middle with an event (Grace is disappointed because her dad cancelled an outing). Depending on how she reacts or responds to the situation her day moves in a negative way (to the left) or a positive one (to the right). It is the same day with different choices and makes it clear that it's not what happens to us. How we respond to life situations is what's important.
