After fleeing a murderous sneak attack from a rival tribe, a prehistoric girl stumbles upon a spiral marked on the wall of a forgotten cave. A grieving psychiatrist is deeply moved by a mentally ill poet who fears nothing except the tall spiral staircase that rises in the middle of the sanatorium. After being accused of witchcraft, a medieval cunning woman is thrown into a river where she glimpses a spiral carved into the rocky underwater bank. A lonely astronaut alters his course when his ship discovers signs of intelligent life in the form of a broadcast signal of the number phi, which is also the ratio of the Fibonacci Spiral. Each lyrically wrought quarter of this multi-layered novel, which author Marcus Sedgwick claims can be read in any order, revolves around this mysterious shape that appears over and over in human history, folklore and nature. Figuring out how each story relates to the others is a puzzling treat and I can’t imagine any reader not giving a gasp of delight and satisfaction when reading the very last paragraphs, which cunningly come around full spiral. As cleverly constructed and delightfully complex as Sedgewick’s award-winning Midwinter Blood, I predict Ghosts of Heaven will score just as much critical love in 2015!
