I am very torn on this trilogy. Initially the contribution of familiar faces (Averroes, Robin Hood) had seriously embarrassed me, but the pages rhythm, intrigues led me to read further. But ultimately this need of the author to relate his work to major events, major characters, the great myths (Cathars, Templars, skinners, and so on) that the crux of the story comes off, as me in the middle of the third volume. This is unfortunate because the characters no "mythical" are brushed with consistency, which proves that the author did not need to look (almost always) to link its frame figures or known facts.
