What happened to Tatiana de Rosnay? This novel is not worthy of his talent ... Is it possible that this is the same person who wrote "Sarah", "Moka", "Boomerang", "heart of another" and all his novels I devoured, and could write this thing indigestible and uninteresting ??? The characters are totally endearing. Like his hero, it seems that she sorely lacked inspiration ... The chapters follow nonsensical. Also very attractive summary is false: "Nicolas is embarking on the track of his origins, until Saint Petersburg" ... in the last 10 pages, yes !!! Really extremely disappointed, I think that if this novel was not "labeled" Tatiana de Rosnay, he never found a publisher Tatiana ... we must revenge !!!
