The listing, Druids by Morgan Llywelyn has ended.
I usually have trouble reading novels based on historical events, mainly because the outcome is obvious. Nonetheless, I found Morgan Llywelyn's 'Druids' a delight to read.
The plot is fairly simplistic and easy to understand. We follow the boy Ainvar as he has his first awakening when he somehow revives his grandmother from death at a Druidic ceremony, to his eventual role of Chief Druid, and advisor to one of the greatest Celtic warriors.
The characters are all very carefully woven, and interesting to watch develop. If you think you know a character, then they will often suprise you with new aspects surrounding their personality.
Finally, this book is quite emotional. There are many heart-breaking events, but they all seem to be handled in a wonderful fashion, and they aren't used as useless plot points.
The romance may bother some, 'Druids' doesn't preach monothesic relationships by any counts. The main male seems to get himself involved with about three women at the same time. This didn't bother me however, and it is written in a 'classy' style and not in a fashion that would insult a woman.
I reccommend this novel to practically everybody. (Except, perhaps, historians who could probably find many errors) Read this if you want an engrossing tale.
