The Last Cato

It seems that Dan Brown wasn't original even with his plot idea: following an ancient church secret by taking your characters in a quest around Europe. The Last Cato by Matilde Asensi, which was written before "The DaVinci Code", takes the reader into a quest to discover the "earthly paradise" as described by Dante in his "Divine Comedy". This is the initiation process to become a member of a secret society that is the keeper of the True Cross. The book is full of historical references, but the style is better than Dan's Brown as all these details are better integrated in the overall story. The ending was not very good, as the description of the "earthly paradise" is not credible, but since no such thing could ever exist it's hard to imagine it in a convincing way, especially that it is setup in middle age technological era.
