rived at a fine combination here: few words and images, but not too few, and well-chosen to pave the way out of the grumps. The artwork possesses substance and delicacy. Really well turned, with balance, momentum, and all the right notes."--Kirkus Reviews starred review

STARRED REVIEW! "This charming account of handling emotions is a great addition to other children's books about grumpy behavior."--School Library Journal starred review
