This is a soul-searching book. The protagonist is looking at his life. He is a career frustrated paleontologist searching for a holy grail, any holy grail.
Stan, the paleontologist, draws his friend Umberto into his obsession. Stan has a clue to a huge discovery in the mountains. He accompanies Stan into the mountains to look for an unlikely fossil.
The Alps are erratic and unforgiving. Stan is no longer young and is the hold back for the trek. Peter is an ancillary character that seems to have little to add to the plot except for his puppet.
Stan spend some flashback time looking at his troubled childhood.
The details on the glacier are well done, you feel a chill as you read.
This book may have been received free of charge from a publisher or a publicist. That will NEVER have a bearing on my recommendations.
