Thank you @hernyholtbooks @macmillan.audio for a copy of this book. 

I am a sucker for books about cults and add in twins and I am in. Kat was in an accident and has temporary amnesia and it's up to her mirror twin, Jude, to help her rebuilt her past. The story is told in dual timeline and both sister's POV. 

There's so many elements of mystery in the story with Kat trying to piece her past together and learning that Jude is keeping secrets from her. Kat is losing trust in her sister and I love how the story unfolded. 

The dual POV added a great element to the story and there were so many twist and turns which I loved. 

The narrators did a great job with the story.
