The second part of Marcin Wolski's trilogy. It is very easy to classify it as an “alternative history” and “adventure fiction” genre, since it contains both historical figures (possibly from an alternative history): Richelieu, Mazarin, Cyrano de Bergerac, aliens from outer space with unimaginable technologies and dizzying adventures in the style Indiana Jones. But the motive of searching for ways of coexistence of science and religion, of opportunities to make progress “more humane” is very strong in the book.
