This was a YA or middle-grade novel that I read in the late ’90s. It was a very loose Greek myth retelling that mashed together many familiar mythological elements into an original plot. Possible characters: Perseus, Medusa, Pan, Echo, Iphigenia. Some or all of it took place on an island which had a network of caves. One of the characters–maybe a plucky young girl–was stranded(?) on the island and encountered someone who became a friend/ally while exploring these caves. I also remember music magically wafting through the caves. Maybe that’s where Pan comes in?

The copy I had was paperback with some blue and purple on the cover. The physical book and style of writing didn’t strike me as “old-fashioned,” so I’m guessing it had been published in the ’80’s or ’90s…but I could be wrong about that.

I’m fairly certain the author was a woman.

Thanks so much for helping me solve this mystery! I remember absolutely loving this book.
