There is an awful lot of this filler. Then there is the irritating sensation of head-hopping, as the narrative flits between a handful of doomed passengers: a banker with a cocaine habit; a Filipino woman who claims to have “lived many lives in many bodies”; and an ill tycoon who is vile to his nurse. Most are unpleasant specimens. When they finally die, it is almost a relief to be parting company with them. The reader is left with the niggling feeling that Napolitano hasn’t made the most of her compelling material and intriguing premise.
