Hugo is obnoxious, cynical and bitter with self-loathing, so a thoroughly unpleasant person who has chosen to be a hermit. His choice of suicide to end his life (spoiler alert) is thwarted leading to a not entirely satisfactory ending but the writing is excellent throughout. (You may remember that I recommended another Christensen book last month, The Great Man)
