I suggest Lord of the Flies or The Giver. Lord of the Flies is about a group of boys who get stranded on an island and start to give in to savagery......The Giver is about a dystopian society (one extremely controlled by leaders and aims for perfection, a bad version of utopia), where certain people are hired to retain the memories of the past to advise their community, who know nothing of worldly issues now that they live in a so-called "perfect" world, and a boy named Jonas is assigned the job of receiving memories from a man named The Giver, the only man with memories of the past....
