This is a fascinating, genre-bending book that takes place over 150 years and seven lifetimes. It also is designed to be read in two different directions – from front to back, or by using the “Baroness sequence,” which is outlined in a note to the reader and with an icon pointing to the next set of pages, similar to a Choose Your Own Adventure book. The novel’s main theme is “crossings” – a version of soul metempsychosis, or the reincarnation of one soul from one body to another. The book is a puzzle box, a romance and an imaginative supernatural tale.
