I hesitated to put the title to my review "A book ultimately disappointing" but the adjective "average" prevails because I still enjoyed the beginning of the book. The world of the Druids seemed interesting with huge potential to dig, then there is a mystery to solve with this massacre committed nothing is known of the guilty ... But the first tier of the past book, everything becomes much more static, the plot more or nothing to advance that ultimately everything is revealed in a flashback rather longish and unexciting ... But above all, that of fighting scenes! "The Battle of the Cité-Root" was ultimately a much more appropriate title to the book. I think one tier of the book consists of detailed descriptions of sword blows, knife, claws ... and I had to force myself to finish it. This is not a bad book in itself but I am disappointed by his appearance, I expected something more mysterious, initiatory, and less oriented "action".
