From the publisher: Shan Shelton is going to the store for his mother. If he had a dime, he could buy his favorite treat, a chocolate bar and a lemon soda pop. Shan knows that Mr. Conley, the storekeeper, pays a penny each for good used paper sacks returned to the store. There are ten sacks at home, but Shan’s mother tells him to take only nine to Mr. Conley, because the tenth sack has a hole in it. Shan wants a chocolate bar and lemon soda pop so much, he disobeys his mother and takes the tenth sack. … And, sure enough, Mr. Conley overlooks it. But as soon as Shan begins to eat his chocolate bar and drink his lemon soda pop, he discovers something is wrong – inside him, and all around him.
