I really liked Marcos Calveiro's first book, 'Festina Lente', I have to admit. So perhaps my cold reaction after 'Settecento' can be related with the vibrant passion transmitted by the previous one. On the one hand, the annoying details of 'Festina Lente' are still present, even increased, in 'Settecento': foreseeable adjectives, stereotypes (Venice is a five landing strips' airport for stereotypes) and, in this particular case, the use of sentences randomly written in an ahistorical Italian, as disturbing as a fake Italian restaurant in a British town.
On the other hand, however, the positive elements of 'Festina Lente' have been removed, and they remain only in the "Galician" section: that perfect balance between setting and action underpinning those great historic thrillers as 'Festina Lente'. Action here is confused, even lost: there are too many plots for the novel's short length, stories and characters are only outlined, and the end is quite abrupt and inelegant.
Then, why three stars and not only two? Because, despite these problems, Calveiro has created an interesting story, has depicted some beauty's scenes, and has played with history in a quite entertaining way. And he's a talented writer in a stumble.
