Never heard of it!

Have you ever heard of this children's book series - The Children of Green Knowe by LM Boston. Apparently it was big in Britain in the 1950s and is based on the old old house the author lived in. Fascinating series! Netflix has a movie version of book 4 called Time to Time (not the correct title of the book, but its hollywood)- and I think the BBC made a tv series about it years ago. I can't believe I have never ever heard of this series! Watching the movie now :)
