I had not heard of this author and ordered the book from my book club because it was a bargain.
A very complex novel, with layer upon layer of lives inter-linked through almost a century. The author keeps the reader guessing about the nature of the connectedness of the characters. Just when you think you have worked out the details, Rayne very subtly changes the whole scenario.
Research seems to have been good and most of the historical details, as far as I can see are appropriate to the times. There are a few little niggles for me, though. It is early 1980s when one of the characters sets up in a rented cottage in the Norfolk countryside and she buys the cheapest mobile phone she could find. Where? At that time, "mobile," phones were mostly car phones and very few people used them. Would there have been an adequate network coverage in the Norfolk countryside in the early 1980s?
The character also does not want to apply for a credit or debit card. I don't think debit cards were widely available at that time.
The last of my, "niggles," is that the character writing her diaries in the early 1900s keeps going in and out of a particular way of speaking. Her language is not consistent. She is a middle-class lady of that time, who sometimes seems to go into later 20th Century speech.
Having said all this, and I think the editor should have picked up on the details about mobile phones and debit cards, this is a good read and I have been kept awake by this book, telling myself, just to the end of the chapter, and half an hour later, I am still reading!
