Things that go: construction
Emotion: Patience, balance, take your time

Eff it, I'm giving it 5 stars. Harper achieves so many things in this highly attractable book. One day, Little Green says his first word: go. Excited to share his word with the world, he bounces inside of an empty stoplight and shouts it for everyone to hear. Waking from their naps (holding adorable things such as a blanket and teddy bear), the construction vehicles wake up and zoom to action. Little Green persistently keeps shouting "go, go, go!" making the trucks go faster and faster until things start going too fast and mistakes are made. Just in time, a Little Red stranger rolls into town and declares "Stop!" Little Green and Little Red, perched inside their stoplight, have a hard time finding balance with their passion for shouting but they finally find a resolution: "Go! Go! Go! Stop!"

Fantastic, bubbly pictures with cute, funny asides make this a showstopper sure to please those looking for a legitimately good story with room for discussion afterwards.
