It is a tribute to Ms. Mandel’s skill as a writer (previous book, the brilliant Station Eleven) that a story about a Ponzi scheme in the economic collapse of 2009 can be both compelling and engaging. It is the psychology of fascinating inter-related characters that is so intriguing: the willingness to seize an opportunity, willful disbelief of reality (if it is too good to be true ..) because of delusions regarding wealth, the simultaneous paradox of knowing and not knowing. There is the enigmatic character of Vincent as a mysterious woman at the centre of the story. And there are hallucinatory ghosts in a spirit world. The story unfolds in a non-linear fashion but all loose ends are linked by the end of the book. Simply put, a great read.
