Dark and disturbing with lots of secrets and lies and add in unreliable narration all makes this a very satisfying psychological thriller!
Told in past and present by Heather (past) and Edie (present) both parts of the story unfold in parallel and I have to say that even though it is quite clear that neither is entirely reliable, the story is cleverly structured and has a very satisfying end.
This is one psychological thriller that is definitely worth its place on your reading list! 4.5 stars.
Thank you to HarperCollins UK and Netgalley for the opportunity to read this in exchange for my honest review.
