It is evident that people have strong reactions to this book. I liked it more than any other Rendell/Vine book, with the possible exception of "Dark Adapted Eye." One of the most fascinating features of the book is the way in which forms of sexual pathology get repeated, with variations, through three generations of a family. Gerald's mother's relationship with her second husband gets echoed in Gerald's relationship with his wife, and Gerald's two daughters act it out in their own peculiar ways, until the very end, when one of them wakes up. There's great insight into what might be called the erotic lives of families, and the writing is first rate.
