Wonderful art, pace, and spots of rhythm and rhyme make this book an absolute smash. Taking the concept of the infectious yawn we all love to hate, this book expands on that idea as one girl fights desperately to avoid bed only to cause a single yawn to leak out, spread, and infect every citizen of the Never Sleeping City. Cute, hilarious, and just an absolute joy to read...if only it didn't resort to that "talk to the reader" gimmick I dislike.
