In this new highly-illustrated series from James Patterson, an extraordinary robot signs up for an ordinary fifth grade class... and elementary school will never be the same! It was never easy for Sammy Hayes-Rodriguez to fit in, so he's dreading the day when his genius mom insists he bring her newest invention to school: a walking, talking robot he calls E—for "Error". Sammy's no stranger to robots—his house is full of 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 square? It's a roller-coaster ride for Sammy to discover the amazing secret E holds that could change family forever... if all goes well on the trial run!

In book two of the House of Robots series, it's 'bot brains versus 'bot brawn in an all-out war! Sammy Hayes-Rodriguez and his 'bro-bot' E are making new friends every day as E works as his bedridden sister Maddie's school proxy. But disaster strikes when E malfunctions just in time to be upstaged by the super-cool new robot on the block – and loses his ability to help Maddie. Now it's up to Sammy to figure out what's wrong with E and save his family!

It's a robot revolt! As Sammy's inventor mom works on a secret project, he and his sister try to contain the hilarious pranks and chaos of droids on strike. After a few early glitches in their relationship, Sammy and his "bro-bot" E are now fast friends. In fact, E is such a valued member of the family that the other electronic occupants of the House of Robots are feeling sorely unappreciated. And when Sammy's inventor mom becomes distracted by a top-secret project, the robots soon begin to fall into disrepair. Cue a robot revolt, with the droids wreaking harmless havoc in the house! Armed with pranks like glue in the shampoo bottles and flying toast missiles, the robots demand to be cared for. It's up to Sammy and his disabled sister Maddie to keep the peace until his mom reveals her secret project . . . and why it was worth the wait.
