The Look-Alike by Erica Spindler is to be released in January 2020. I read an uncorrected digital copy through NetGalley and gave it four stars and a short review:
A well-crafted mystery with romantic threads that furthered the tension - as it was unclear who was the murderer.
There were some technical issues and some editing items that got in the way of my enjoyment of the book. I passed the specifics back to the publisher, so hopefully it'll be even better when it is released in January.
