Taking its title from Buzz Aldrin's description of the lunar landscape, O'Malley uses the words to metaphorically describe the mental and emotional state of Duncan, at the centre of this spiralling novel.
Brought up in an orphanage in the harsh wastelands of Minnesota, his world is turned upside down at the age of 10 when his mother, Maggie, a former opera singer, appears and takes him to her home in San Francisco.
From the isolation of the monastery orphanage and its rituals and structure to his mother's drink-fuelled, unstructured existence, the book spends the bulk of its 401 pages tracking Duncan's search for his place in the world, for a meaning to his existence, and for male role models, whether in the form of his (possibly dead) father, or Joshua, his mother's occasional lover and confidant.
This is no glib, vacuous ride through San Francisco in the 1980s. It's a little difficult to say exactly what it is at all, though: O'Malley has ambitious themes, and a propensity to devote much real estate to swathes of dense text, some of it profoundly moving, some irritatingly overworked.
Although the word is overused, many of the dramatic events and, indeed, the characters themselves, border on the surreal: it's difficult to discern fiction from fantasy, a deliberate ploy, it would seem, to lend an otherworldliness to an already esoteric offering. It is, in a strange sense, Cormac McCarthy meeting The Vintner's Luck: space and silence blended with fantastic leaps of imagination.
