"Innovative, modern and incredibly fun. Rhyming board books are prevalent, but rollicking, fun ones are rarer." --Creators Syndicate

"The subtitle says it all about this hilarious and energetic romp through numbers one to 10. A big-eyed, blue-skinned, and white-haired banshee stirs up trouble by shrieking, wailing, and howling a variety of greetings to her Irish countryside companions, which include dozing hobgoblins, cleaning bog monsters, and meditating druids. The artwork perfectly encapsulates the cartoonish antics and jolly spirit of the work. An inventive take on counting and the concept of quiet time for preschoolers--an easy pick for Halloween, too." --Della Farrell, School Library Journal
