When the author of this picture book falls asleep, the illustrator—personified as a small purple penguin—sneakily decides to write a story. In the illustrator's story, the cute and cuddly Princess Penguin is envious that her older sister, Princess Llama (whose feet smell like cheese), has bigger and better stuff. She wishes on a falling star to send her sister to the moon, and Princess Llama disappears overnight. Princess Penguin briefly enjoys her status as the oldest sister…until it is time to go to bed. Terrified of the dark, the illustrator, Princess Penguin, tries very hard to bring her sister back from the moon. When her various ploys to get her sister back don't work, the illustrator enlists the help of the author (hilariously named Ima Snoozen) to rescue her sister. Offering an actual story rather than resting as a metafictional meditation, Frost's hilarious picture book is rife with bold plot twists and cheeky dialogue. For instance, when Princess Llama gets wished to the moon, the narration reads, "Princess Penguin suddenly felt sad and began to cry." The very next page contradicts this with an emphatic "NOT!!!" accompanied by an image of Princess Penguin dancing under a shiny disco ball. The pictures are bright and colorful, and the illustrator's and Snoozen's texts can be distinguished by a change in the typeface. Tailor-made for readers who enjoy metafictive, interactive picture books. (Picture book. 4-8)
