One of the most interesting elements of this story is the fact the author hasn’t created a black or white situation.
There are many shades of grey, and in this case those shades relate directly to whether the characters are good guys or bad guys. The truth is, there is no clear answer to that question.
The reader feels sympathy with Edie, because of the hard situation she finds herself in. She is a single woman, who is about to become a single mother. When the baby does eventually arrive she is overwhelmed and clearly needs a friend.
Heather seems like the great alternative to a support system, despite the troubled past she and Edie share. Seems like the perfect solution. Edie needs help and Heather wants to help. Does she really want to help though?
Heather has a tendency to stalk, get violent and blackout. She is creepy and clearly unstable. Would you want her to take care of your newborn baby?
Throughout the book Edie has flashbacks to a time when she and Heather were friends and also to some terrible event that ended said friendship.
What it comes down to is who you think is guilty of the greater crime or wrong-doing. There are things that are unforgivable or so inhumane that they leave a deep dark stain on anyone involved in them. Some wrongs can never be righted.
Watching Edie will make you question everything and everyone. It is a nicely paced and well-developed psychological thriller, and despite the fact the reader can probably guess the traumatic secret the two of them are hiding, it is still a compelling read.
