I read a book when I was a young teen in the early 70’s and can’t recall the title or author. It centered around a group of kids who were friends. I think they were very young teens, like I was at the time. They could stop time and go to the world of mythology. I’m pretty sure it was Greek mythology. I recall them being bored in school and being able to do this several times in class. I think they were helping the Greek gods, or at least trying to. I also remember one boy earning a bowl from a god, and in it he could have whatever he wanted to eat by just imagining it. It was the most amazing book–and it obviously left its mark!
Thanks so much and good luck! I’ve been wanting to find this book for many, many years!
