A Pig in the Palace — Ali Bahrampour

A pig is invited to dinner with the queen in this delightfully funny misfit tale
 
Bobo is rolling around in the mud when somebody slips a letter under his door. It's an invitation to have dinner with the queen! “Why me?” Bobo wonders. What will he do at a fancy palace? He's covered in fleas. He doesn't know which fork to use. He has never been anywhere so grand! Indeed, when he arrives, Bobo feels terribly out of place. And trouble is following him wherever he turns! But maybe . . . he's not the only one who'd like to let loose?
For any kids who have tried their hardest to behave at a grown-up gathering, Bobo the boar is just the itchy, clumsy, endearing hero they've been waiting for.
