I have rarely been so tormented during playback ... What we offer Stephenie Meyer in the novel, it is a terrible situation with no apparent solution, absolute torture! This is truly a science fiction pearl in my eyes. The author really knows how to to captivate its readers. I expected no less of her seen his previous works. To summarize some of the history, the Earth finds himself invaded by Souls, taking possession of the living human body, crushing his consciousness there to replace it. But a Soul, Vagabonde, will be put spokes in the wheels by his host, a much higher consciousness than she thought and will resist as much as she can. The story centers on feelings. Not just those of Wanderer and his host, Melanie, but those of all the characters of the book. Because this situation will create many dilemmas for many people ... The author has beautifully recreate the emotions of his characters, with uncanny accuracy. Of course, how to write a good novel without a beautiful love story? Again, it will not be so simple, but complicated at possible! What make us crazy! This book is simply outstanding and it is certain that I reread with pleasure!
