Not So Normal Norbert by James Patterson and Joey Green Hardback Book

Not So Normal Norbert by James Patterson and Joey Green Hardback Book. Book & dust jacket are in great shape. There used to be a small spot on corner of a page I noticed, see image. NORBERT RIDDLE lives in the United State of Earth, where normal means following the rules, never standing out, and being exactly the same as everyone else. He's been normal his whole life - until a moment of temporary hilarity when he does a funny impression of the country's dictator ... and gets caught! Now Norbert's been banished to the Astronuts Camp on planet Zorquat 3, where kids who defy the rules are exiled forever. He's been taught his whole life that different is wrong, but everyone at Astronuts seems crazy creative ... or are they just plain crazy?
