Unknown

When everything has been taken from you... There's nothing left to lose. Martin Harris has been in a coma for three days. When he wakes up, otherwise unharmed, he is shocked to discover that no one knows who he is — he no longer exists. Worse still, another man is living Martin's life. His identity, his home, even his wife have been stolen. He has lost everything. Except his memory... Will anyone believe that he is the real Martin Harris? If not, is he mad? Or is there a far darker explanation?
