Flat Cat was born flat. He wasn't squashed under the lunch lady's rolling pin. He wasn't smushed by an avalanche of library books. He was just flat. And most of the time, Flat Cat liked it just like that. 

Until one day, when Flat Cat, in the mood for a change of scenery, slips into his friend Willow's backpack and accompanies her to school, where he gets folded into a paper airplane, passed as a secret note, and used as a bathroom pass. Will Flat Cat be able to escape the chaos? Or will he realize he is keen to be loved and adored?
