Interesting story that went on for far too long. Sadly the last third of the book gets bogged down in WW 1 details that the author uses to slip in the reason for the "secret rooms". While I understand the authors original intent was to write a book about WW 1, she should have picked the Duke or the war rather than trying to incorporate both into this book. She also seems to have lost interest once she reveals the secret and gives a rather cursory ending. No cuddles at the end for this author--wham, bam, thank you ma'am and see you later. But then again it's about a Duke!
