This book started off very well, with a very readable style and intriguing plot. However, as other reviewers have said, as it progressed, the whole thing started to get more unbelieveable. Only the heroine seemed to feel that anything was wrong when her daughter failed to appear, and this gave the plot a bit of an unrealistic feeling.
However, with a decent ending, this would not have mattered so much, and it would have still have been a good book. The real fault with this book was there was no explanation as to the events which had taken place, and why things been done. I was hoping for an explanation; or even better still, a last minute twist right up until the final page. Unfortunately, neither came.
