Really enjoyed The Nightingale by Kristin Hannah. Also, been reading a number of books on Gaslighting. The best so far is Gaslighting by Sarkis, Stephanie. It is something everyone should read IMO. It is shocking behavior. A person does not even know it is going on. Turns out my MIL was also a covert narcissist too. After being told about this, I see this behavior in a few other people I know.
