Bad Mommy by Tarryn Fisher is one of the best psychological thrillers I have read in years of reading psychological thrillers. It is a five-star plus Amazon read which I highly recommend. I didn’t even mind paying the full Amazon price of USD 3.99. It has a very different organizational style which almost makes it three novels in one while still having one easily recognized theme and story. The three parts; The Psychopath, The Sociopath, and The Writer, tell one disturbing and twisted story in fifty-two chapters from three points of view. I liked the title of Chapter fifty-two; Chapter One.
