The Scrambled States of America

Keller's first book, The Scrambled States of America, was released by Henry Holt Books for Young Readers in 1998. Uncle Sam tells the story about the Kansas, one of the 50 states of America becoming bored of where he is and organizing a party with Nebraska, Iowa, Missouri and Illinois, where the states meet each other and decide to trade places. The states enjoy their new locations (Nevada and Mississippi fall in love as a result.) But soon they become tired and want to move back to where they were before.

Publishers Weekly gave the book a positive review, noting that "hits hard to imagine a more engaging (or comical) way to learn the 50 states and their locations."^[1]

• A tie-in card game of the same name was published in 2002 by Gamewright.^[2] It is a two to four-player game geared toward players 8 years old and up.

• In 2008, Keller followed up with a companion book, The Scrambled States of America Talent Show. New York comes up with the idea of having all the states participate in a talent show. The states eagerly agree and prepare for their acts. However, Georgia has stage fright and is worried how her performance will go. Kirkus Reviews believed "this exuberant geographical jamboree will definitely leave readers in a state."^[3] The book was a Junior Library Guild selection.^[4]

Open Wide: Tooth School Inside

Open Wide: Tooth School Inside was Keller's second book and was released by Henry Holt Books for Young Readers in 2000. It tells the story of a day in a tooth school, with all 32 tooth students present. The book reviews the biology of teeth, tooth care, and teeth in history.

It's very funny and made me laugh every page."^[8] "This book, with comic type illustrations, will entertain children who enjoy humor, puns, and silliness."^[9]

Do Unto Otters: A Book about Manners

Do Unto Otters: A Book about Manners was released in 2007 by Henry Holt Books for Young Readers. Keller brings the "Golden Rule" to life in the form of Mr. Rabbit and his new neighbors, the Otters, who show kids that a simple "please" or "thank you" goes a long way in making friends, while animating every page with their well-behaved hijinks.

This book was a Junior Library Guild selection.^[10]

Weston Woods distributes a fully animated version of this book on DVD under the same name.^[11]

Kirkus Reviews stated "While kids may well have encountered the Golden Rule elsewhere, this explanation and elaboration nicely unifies what might otherwise seem like a dreary list of manners. This lively book is anything but."^[12]

Birdy's Smile Book (2010)

Kirkus Reviews found that "The collaged illustrations are bold and textured and occupy white space in Keller's characteristically exuberant style." but "The narrative voice and illustrative feel ... are at odds with much of the content, which requires the sense of humor and irony of an older child. Whether they will embrace the presentation and Birdy's exhaustive salute remains open to question."^[13]

Potato Pants! (2018)

Potato Pants! was Keller's seventh book and was released by Henry Holt Books for Young Readers in 2018. It tells the story of Potato and his eggplant nemesis, who struggle to find the perfect pants. The Weston Woods adaptation, released in 2019 and narrated by a full cast, was directed by Galen Fott.
