What is "myth-o-mania"

Myth-o-Mania is a series of books for children by Kate McMullan. Each book is a parody of a different Greek myth starring Hades, the god of the Greek underworld. The books are never identical to the original myth, as they always put Hades in a positive light and claim that Zeus is a liar and made up the original myths in order to promote himself. The traditional hero of the myth, such as Theseus or Hercules, is usually portrayed as a fool or an oaf. Hades has to help the hero complete the quest. There are other differences between the original myth and the myth in the book; these are often humorous or given a modern twist. For example, Elysium (Heaven) is a perpetual rock concert.
