Query: A Gripping Psychological Suspense Thriller

Since the previous review have gone over a good synopsis of the book, I would wish to praise Ms. Rose for yet another great work. Her research of the material was thoroughly thought out. In spite of the romance factor integrated in the story, it did not undermine the purpose of the plot. Kept me guessing until the end.Kudos Ms. Rose.
