I can't remember the last time I read a book that consumed my every thought when not in my hands. Much like the fictional book this story is based on, I was haunted. 
Absolutely phenomenal writing telling the tale of historical fiction mixed with modern day witchcraft, intertwining the 2 perfectly. So many twists and turns along the way, C.J Cooke absolutely had me in her grip, I couldn't get through this book fast enough. I especially love the Authors Note at the end, delving into the history and research that brought this book to life, and the very real people it is based upon. 
Allison's POV, although harrowing and heartbreaking, doesn't venture too far from what you would expect of a story based on Witch Trials, unfortunately the details we do know are so horrendous there's not much else to add, these chapters did feel like every other book I've read about witch trials. 
It is in the POV of Clem, and her daughter Erin that this story really shines, and they way Cooke merges the lives of these 3 women together, across hundreds of years. 
This is the first book I've read by C.J Cooke, although The Lighthouse Witches has been on my radar for a while, I will absolutely be diving headfirst into her collection. 

Thank you NetGalley & Harper Collins for this e-ARC.
