A book that delivers Completion end. The first part of the book is made with 2 stories, short chapters, a dive in the well-written time, a detailed documentation of this disturbing character that is Nicole Flamel. For the second part Ravenna and Giacometti rajoutent us new data, a regular newsletter on the price of gold and the mysterious organization Aurora. This little world, which apparently has nothing in common, comes together brilliantly to a final in Paris.

A marked route, a kind of treasure hunt, puzzles, chases, Marcas a great form, increasingly expanded, in front of this "Blood Brother" for whom killing has become a divine mission.
