The #1 New York Times bestseller, perfect for fans of Diary of a Wimpy Kid!
 
An extraordinary robot enters an ordinary fifth grade class in this hilarious, action-packed start to the #1 bestselling series from James Patterson!

Sammy Hayes-Rodriguez has never really fit in, with an inventor mother, a graphic novelist father, a lovable little sister with an autoimmune disorder…and house full of robots. So he's dreading the day when his mom insists he bring her newest invention to school: a walking, talking robot he calls E, for "Error". Sammy's no stranger to robots—he lives with a colorful cast of them—but this one not only thinks it's Sammy's brother . . . it's actually even nerdier than Sammy.
 
Will E be Sammy's one-way ticket to Loserville? Or will he prove to the world that it's cool to be smart? It's a roller-coaster ride for Sammy as he discovers the amazing secret E holds that could change his family forever . . . if all goes well on the trial run!
 
“A fast-moving plot, lots of jokes, and a host of weird robots will draw readers in, especially those looking for books similar to series such as ‘Diary of a Wimpy Kid.’’”—School Library Journal
