Girl unknown

Girl Unknown A Novel by Karen Perry published by Henry Holt & Company. An arc of this novel was given to me through Netgalley for my honest review thank you to all parties for the opportunity. It is very unique in a number of ways. The first is that Karen Perry is actually a pen name for two writers collaborating on this book. This is the first book, to the best of my knowledge, that I've read penned by two authors and it definitely worked here, you could not tell who wrote which part of the story and it made it easy to read and a real page turner.
I have to be honest when I picked this up I wasn't sure what to expect. I loved the way the authors split the chapters up between Caroline and David I feel both perspectives help to round out the story giving the reader an insight to what is going on. What I like to call Zoe Barry is a bombshell on a family who was coasting through life happily. Everything is fine until “She” arrives, and while at first, I felt horrible for her, toward the end chapters I was convinced she needed more help than anyone can give her. Is she his daughter, is she a stranger or is she just the killer? As far as books go I found this nicely paced with characters well-crafted and an ending that you will either see coming a mile away or not figure it out until the last page. 4 Unbelievable Unknown Stars from me.
