A tale about mischief and adventure. Meet Max, the emotionally unstable wild boy who dreams up the island of the monsters, travels to their home, tames and masters the wild creatures. A heartfelt tale for any boy's heart. It took two years before children's libraries would hold the book in their collections because of the wild beasts when it was first released publicly. It is one of the few so beautifully illustrated children's books to address and analyze anger. Sendak often revisited this theme in his work; where he would address negatively viewed emotions like jealousy, boredom, and frustration. He was interested in depicting how children master these feelings and come to terms with the reality of their lives.
