A constant effort reading

The first paragraph is oppressive, disturbing, memorable. It suggests the rest of the book whose tone hardly changes ... Despite an obvious interest in the gripping story and the characters, I had to make an effort on the duration of playback, so the atmosphere is heavy, exacerbated feelings, flood scenes. I think we are far from writing quality of a Goncourt is in my opinion a good historical thriller, with unfortunately many lengths, uneven rhythm, repetition, some shots.
