I thought this story had more potential than how it ended.

The dissociative personality storyline had some holes. After a slow game of cat and mouse, the final chapters felt rushed trying to explain everything. The vengeance felt like a blip. The sister's storyline is completely ignored, I hope the author addresses her side as it looks like she was having issues of her own.

Still, it kept me engaged and wanting to know more of how things were going to resolve themselves.
This book would appeal to fans of The Ruinous Love Trilogy, Credence, Identical, or Into the Darkness series.

The author graciously provided a free advance copy for review, opinions are my own.
