Cadfael a Rare Benedictine: The Advent of Cadfael
I have watched a lot of the TV series of this collection of books, and read a few as well.
This is the long awaited how did he become a monk in the first place with a couple of early stories added in. Ellis writes well, the character is well rounded and believable, the stories problems he gets mixed up in are also believable. Ellis has a good grasp of the history of the period and that comes out in the way the stories and background fit together.
A good read.
