Here's a breakdown:
* Early readers (ages 4-7): "The Enormous Crocodile," "The Giraffe and the Pelly and Me," "Revolting Rhymes," "Dirty Beasts"
* Middle Grade (ages 7-12): "Charlie and the Chocolate Factory," "Matilda," "James and the Giant Peach," "The BFG," "Fantastic Mr. Fox," "The Twits"
* Young adult (ages 12+): "Danny the Champion of the World," "The Witches," "Boy" (autobiographical), "Going Solo" (autobiographical)
Here's why it's difficult to put his books in a strict age range:
* Dark humor and satire: Dahl's stories often feature dark humor, satire, and even a touch of the macabre, which can appeal to adults who appreciate his clever wit.
* Universal themes: His stories explore universal themes like family, friendship, kindness, and overcoming adversity, making them relevant to readers of all ages.
* Complex characters: Dahl's characters are complex, with flaws and strengths, making them relatable to both children and adults.
Ultimately, the age appropriateness of a Roald Dahl book depends on the individual reader and their maturity level. Many adults find his stories just as enjoyable as children do, and children who are mature for their age may appreciate the nuances of his writing even more.
