The Hypnotist's Love Story by Liane Moriarty
If you loved Big Little Lies, you'll love this other twisty tale by Liane Moriarty, and we think it should be made into a hit movie, pronto. Ellen is a hypnotherapist, and she's in love with Patrick, who strangely enough has his own stalker. But Ellen doesn't mind. She's fascinated by it, in fact. But what she doesn't know is that the stalker Saskia is posing as one of her clients, and that her obsession is on its way to crossing a line. It's totally addictive; you won't be able to look away.
