I'm currently half way through a book by Mary Stewart called "The Crystal Cave" which is essentially a story about the early life of Merlin. What with my particular fascination for this character, it's hardly surprising that I picked this as the first fiction book to read in 10 years (all my other 300 have been non-fiction - it's not that I don't read or nuffink!).

I highly recommend it for those with an Arthurian interest, or those who want to read an action adventure with lots of druidry built in too. It has the most beautiful engaging prose I've read for ages, and I am really enjoying it. She has managed to completely weave a convincing spell of realism around this mythology and had brought the whole story to life wonderfully.
