Question: Is their a name for the opposite of a coming of age tale!?

A novel where instead of growing in character and in maturity, a person regresses!. For example, the ending section of Huck Finn where Huck loses all of his independence and goes back to following Tom Sawyer!.

If their is a name, is their a fancy literary name too!? Like a coming of age tale is a bildungsroman!?Www@QuestionHome@Com

Do you mean something like Hook (a la Peter Pan)!? Age regression is a common enough theme in fantasy, science fiction, and other genres, but I can't think of another name for it!. Sorry!.Www@QuestionHome@Com
