Simply thrilling. Its surprising denouement works a retrospective magic. - New York Times Book Review "Van Cauwelaert has assembled his plot perfectly， like an intricate timepiece， and we are amazed by the precise ticking that sounds at every twist in the tale. The book reads like a close cousin of Philip K. Dick， the acknowledged master of doubting what s real."- Olivier Delcroix "A devilishly well-oiled plot， which grabs the reader with both hands， drags him along， and twists him around."- Le Spectacle du Monde Martin Harris returns home after a short absence to find that his wife doesn t know him， another man is living in his house under his name， and the neighbors think he s a raving lunatic. Worse， not a single person—family， colleague， or doctor—can vouch for him. Worse still， the impostor shares all of Martin s memories， experiences， and knowledge， down to the last detail. He is， in fact， a more convincing Martin than Martin himself. Is it a conspiracy? Amnesia? Is Martin the victim of an elaborate hoax， or of his own paranoid delusion? In his high-powered new novel， Didier van Cauwelaert， the award-winning author of One-Way， explores the illusory nature of identity and the instability of the things we take for granted. Dispossessed of his job， his family， his name， and his very past， Martin Harris is an Everyman caught in an absurd and yet disturbingly convincing nightmare， one that seems to have no exit and that resists every explanation. Part moral fable， part Robert Ludlum-style thriller， Out of My Head is a fast-paced tale of one man s desperate attempt to reclaim his existence—even at the cost of his own life.
