I loved it. I gave it 4/5 stars.
This is a Phantom of the Opera retelling that takes place during the London Blitz. And it works.
It flips back and forth between present time and WW II. It did drag a bit at times hence why I only gave it 4 instead of 5 stars but all and all I loved it. I would greatly recommend you give this book a try.
Once you make it in a little over 160 pages the action kicks in big time and you will not be able to put it down till the last word of the last page.
I have to say what I loved so much about this book was how It flowed so easily between the present time and back to the 40’s. I never found myself dreading the time switches. I actually did not see the ending of this book coming. And being a person who loves mysteries and read mysteries for the last 20+ years that is a rare thing.
