Fans of John Connolly need to be aware that this is not a book in the Charlie Parker series. Although Charlie Parker makes some brief appearances in this book, he is not the main character. Once again, Connolly, an Irishman, writes with sensitivity and detail about Maine and other parts of the United States. In this book he begins with an historical event set on one of the islands off the coast of Maine. As always, ghosts and the supernatural come into play. There is significant violence and description of a relatively gruesome events in scenes. It is not a book I would recommend to adolescents. Both the plot and the writing make it clearly an adult read.
Conley writes with relative sophistication blending historical fiction, religion, and geography with strong plots and characterization. His plot and characterization grab the reader immediately and will keep you reading.
