Who is "Synthia," who is she. or it? Lee's life is complicated; he moves through a richly textured experience, of love and loss, romance and passion, with Millie, and at the last, with Sam, and all the while he feels that his every move and statement is being mysteriously controlled by an alien being. a voice in his head, guiding and directing him, who he names "Synthia." Lee struggles to come to terms with this intrusive, incomprehensible presence in the most detailed and private areas of his personal life - but, paradoxically, the advice he receives from "Synthia" is better than that of his old Rugger Club friend, Jerry. But. who or what is "Synthia," and what is her - or its - interest in Lee? This is the enigma that unfolds in Mind Out - an absorbing psychological study that perhaps asks more questions than it answers.
