Today, the day before christmas .. a group of volunteers willing to participate in a somewhat strange experience, led by a strange doctor in an old institution specialized in psychiatric problems.
In the past, the day before christmas too, in the same Locations, Caspar (newly arrived patient and completely amnesiac) some patients and medical staff find themselves stuck in a storm accompanied by a psychopath ... survive the group-t there that night? and what connection between these two eras?

Sebastian Fitzek became known in the field of psychological thrillers, through his novel "therapy" (in which he made a nice nod elsewhere) and proposes here once again an extremely novel where he macchiavélique is difficult to see the ending coming ...
However, I admit that it breaker soul I was not as impressed as his previous novels.
It lacks a bit of survival ryhtme, Fitzek failing to maintain the tension ... the fault probably a lack of real twists during much of the novel. And I've never managed to attach myself to the characters ...

The beginning seems very slow to develop, time to get to know the characters .. but even when survival really begins, Caspar struggling to counter the "breaker of soul" while trying to regain his memory seems to be the key to everything, struggling to convince .. the mystery does not catch the reader ..
yet the scenario set up by S.Fitzek is intelligently thought .. I did not see coming, the big rebound that dramatic night, and all explanations have appeared to me rather convincing ...
The final outcome (which links the two periods) is against duller ...
In short, it's still a pleasant time reading, but below what we already offered this author ..
