After the success of "Frozen" and "Circle" Bernard Minier recurrence and is now part of the list of writers I revere literally ... Not without making me think "Just a shadow" and "Wedding Dress" because these two books are also placed under the same theme .... but what a performance WHEN IT comes to the characters sink into dementia, madness .... I strongly recommend this book which holds in suspense throughout and offers little respite, and for those who have not read the previous titles, know that it is not essential even if we find some characters and references to certain passages. To give you a little water to the mouth without saying too much, Christine drift off and lose complete control of everything connected you to the certainties that make your day .... But ultimately that manipulates that ??? And how will be completed this long and painful decline ???
