Warning, the term "thriller" affixed to the cover of the book is a bit excessive. Is a novel from causing that leaves to reflect on the phenomenon of involuntary disappearances, and holds spellbound it right! The alternation past / present is worked, the pieces assembled with talent, and intact until the end suspense. My only "complaint" would be that after such mouthing is expected suddenly to a "huge" outcome, which was not the case in my opinion. I regret that the author have not dug more complex even perverse connections established between the characters.
