Thank you @bookmarked @netgalley for a copy of this thriller. This story is full of unreliable characters and the clinic location makes a perfect atmospheric thriller. We have Meg that goes undercover to the clinic as a patient to learn more about her sister's death. Of course, the clinic is full of celebrity patients and they are fighting some kind of addition. I appreciate how the author depicts what a patient goes through physically and physically with withdrawals. I really didn't know who the killer was and kept me guessing. I would say that you would have to suspend your belief a bit for the ending.
