I love Mary Stewart books! I've tried to find & collect all in that series before I start reading them. <3
We had the good old Encyclopedia Britannica reference tomes to pore through. Good times.
You may also be interested in reading some Juliet Marillier then. I'd recommend The Bridei Chronicles. Historical fantasy, interwoven with legends & facts.

I am not sure but I believe fifth book, a prequel, has also now been published. It has been many years since I read these. But they out doall others telling of the Arthurian legend.
Thank-you, I don't believe I've come across J. Marillier. I will look her up, maybe comment later after a read. I actually go hard-copy library, but thanks for www site.
The website was just to reference her books so you could get a feel for them. I hope your library has a copy of the series. :)
Today I managed to find a copy of Mary Stewart's The Wicked Day - score! :D
