Holes is a Newbery Medal-winning novel by Louis Sachar.It was later adapted into a screenplay for the 2003 film by Walt Disney Pictures,which starred Shia LaBeouf and Khleo Thomas and was a critical success.
Stanley Yelnats IV is an out-of-luck teen who suffers constant misfortune as a result of a curse placed on his "no-good-dirty-rotten-pig-stealing-great-great grandfather".When sneakers suddenly fall from the sky and hit Stanley,he finds himself in a whole new type of bad luck as the sneakers were a special donation to a charity from a famous baseball player Clyde Livingston,and the police convict Stanley of this crime that he didn't even commit.With the choice between jail or a juvenile correction camp,Stanley chooses the latter,and thus arrives at Camp Green Lake.There,Stanley and the other boys are forced to dig holes five feet deep,and five feet wide in the now dry bed of the camp's eponymous lake every day.Stanley eventually realizes that they are digging these holes because the Camp Warden is searching for something likely hidden in the lake bed.As Stanley continues to dig holes,he befriends the other boys at the camp,and learns to adapt to this new misfortune.
Stanley’s great-great-grandfather,Elya Yelnats,was from Latvia.When he was 15 years old,he fell in love with a lovely 14 year old girl named Myra Menke and wished to marry her.However another man named Igor Barkov,a 57 year old pig farmer,wanting to also marry Myra,proposed to her father with a large pig.Elya,for he could not offer a pig to Myra’s family,went to an old friend,Madame Zeroni,an old Egyptian woman with only one foot who tells Elya that Myra is only dimwitted and weak and is unfit to be his wife.She tells Elya to go to America like her son has.Elya becomes sad and Madame Zeroni gives Elya a small pig.When Elya complains the pig is too small to be presentable,she teaches him a song that he should sing every time he brings the mountain where the pig will drink from the stream.If he does this daily for a month,the pig will grow to be even bigger than Igor’s.Then Madame Zeroni makes Elya promise that when he has presented the pig to Myra’s father and proposed,he will take Zeroni up to the mountain herself,let her drink from the stream and sing the special song.If he should not,Zeroni warns that a curse would be placed on Elya’s family for generations.However on the day that Elya presents the pig to Myra’s father,his and Igor’s pigs are exactly the same size and Myra’s father then turns to Myra to choose her suitor.When she cannot decide,Elya realizes just how very stupid Myra is and thus goes to America,forgetting his promise to Madame Zeroni.He marries a smart and strong woman and names their son Stanley Yelnats because “Stanley” is “Yelnats” spelled backwards.They continue to have bad luck through their lives and into generations to come because of Madame Zeroni’s curse.
