by Mary Stewart
I had forgotten that I re-read this when the author died, so my review is basically a repeat of a previous one because my opinions haven't changed.
First off, the writing is excellent. I was deep in this story in a way that would normally generate 5 stars. The only reason it only got 4 is because towards the end, the artistic licence that an author of Arthurian fiction must necessarily take veered off into a direction I could not rectify historically.
One of the strengths of the story is that it has a lot of genuine historic references so that the tale of Arthur is painted against a backdrop of known facts. Ambrosius did come to England and route the Saxons in the year given; Vortigern and his son Vortimer are actual historic figures. Vortigern did try to build a stronghold in the place depicted, only to have it fall down time after time because of geological anomalies that Engineers of the time didn't understand.
Merlin himself is depicted as a very believable character, with the sole exception of his attitude towards Christianity near the end. I'm not anti-religion or anything, but a near-conversion doesn't work for Merlin. One could argue about the transitions of Paganism to Christianity around that era, but a student of history will know that it's about a thousand years too early in the fifth century for that level of flexibility between the sets of beliefs.
Despite that, I really enjoyed the book and had trouble putting it down.Again. Mary Stewart has a talent for bring her characters to life.
One thing I'll add, I saw this T-shirt ad while I was reading and made a direct connection. If you're reading the book, you'll see why.
