Stalwart friends Piggie and Gerald the elephant push the metafictive envelope in a big way when they realize that "someone is looking at us." Is it a monster? worries Gerald. "No," replies the squinting Piggie. "It is... / a reader! / A reader is reading us!" How? wonders Gerald. Piggie drapes herself on a word bubble to demonstrate: "We are in a book!" "THAT IS SO COOL!" Joy leads to a little bit of clever practical joking—Piggie figures out how to make the readers say "banana" out loud, and hilarity ensues—which gives way to existential angst: "The book ends?!" exclaims an appalled Gerald. Emergent readers just beginning to grapple one-on-one with the rules of the printed codex will find the friends' antics both funny and provocative: Just who is in control here, anyway? As always, Willems displays his customary control of both body language and pacing even as he challenges his readers to engage with his characters and the physicality of their book . The friends' solution to the book's imminent end? "Hello. Will you please read us again?" You bet. (Early reader. 4-8)
