Zack Delacruz me and my big mouth

Twelve-year-old Zack Delacruz has remained happily unnoticed at his middle school... until now. When he sees his classmate being teased by the school bully, Zack surprises everyone--including himself--by breaking out of his shell and standing up to the tormentor. Somehow this act of bravery gets Zack put in charge of the sixth-grade dance fund raiser with none other than the bully himself! Zack's situation goes from bad to worse when he learns that his best salesperson for the chocolate bar fund raiser has been EATING--not selling--her candy bars. Zack never wanted to be the class hero, but with the hopes of the entire sixth grade on the line, can he come up with a new plan to save the dance?
