This is my fourth Freida book and they have all been soo good! Working in healthcare I love a good Psychological Thriller and you can never go wrong with a Freida book. I love most that her books have this crazy twist that makes me question the whole book and this one did not disappoint. Though it was as quite of a crazy twist that I had planned in my head to happen, the twist still had me rethinking everything I had read in the book. Based in a psych ward where the main character Amy thinks that she is just doing a normal clinical rotation while in med school, but it turns out to be so much more as she learns about the different patients residing in Ward D. It will have you on the edge of your seat as Amy discovers some secrets and has to try and make it through the night alive.
