The Toothache in My School [EPUB ebook] 

Charlie Nada and the students of Sundale Elementary never had any trouble playing by the rules. But when Dennis Bennett moved into town, he bought his own set of rules with him. This new tough guy with the souped-up huffy, bullied his way through numerous children before fixing his sights on poor Charlie. Being bullied is something no child should experience. Charlie never has until now, so how will he handle it? Will he stick to what he had always been taught: 'No one has the right to put their hands on anyone else.’ Can he? Hold on for this gripping ride. It’s a fun one!
