In Engagement, all plot elements are furnished by the narrator. It is one of the protagonists of a game two, perverse, sensual ... and not very clear. The question is whether that which is honest and tells the truth and says if his "companion" is truly one she described, disturbing, dark, dangerous (?). The psychological thriller Chloe Hooper, with a farm house for decoration, looks like a gothic novel. Who to trust? Impossible to know, even once read the very last line. Paranoia, schizophrenia, insanity? What's wrong with one and / or other of the components of this odd couple whose paid sex does not prevent feelings. The book captivated and annoyed at the same time. It is a little too diluted, it maintains suspense with a wealth of details but the outcome is anything but satisfactory. Playful, okay, but a little tangled in her own mystery.
