I was listening to a book with my niece on NPR in 1980, it was about a kid staying with his/her grandparents or aunt/uncle. Upon exploring the house he/she finds a painting. To look at it closer a candle is lit and he/she is transported to an island. I have looked everywhere for this book please help!
It sounds very similar to the beginning of “The Voyage of the Dawn Treader”, a Narnia book by C.S. Lewis, except that there are three children, and they’re transported to a ship, not an island. They subsequently visit lots of islands, though.
