My mother bought me "The Planet that Wasn't" when I was a kid - excellent book that I re-read many times:

This is why I read HN's comments.

I get MANY recommendations for books/movies/shows/topics I knew nothing about etc. here.

Just ordered this book for my 10-year-old grandson.

Maybe I should have mentioned that was about 50 years ago - still a good book though!

I suspect much of it is still relevant.

Well I'm pretty sure that Vulcan still isn't there!
