From Psych Writer:
There is often a strong reaction from readers of my novel, The Sleeping Serpent. The main character, Nico Romero, is a highly skilled charismatic yoga master who manipulates women to serve his desire for wealth and celebrity. One of the most frequent questions I get from readers is, why would a woman allow a man to abuse her? Why doesn’t she tell him to go to hell, and walk away? A codependent relationship with a narcissist is as addictive as cocaine. It’s an obsessive compelling force. Unwittingly, it can happen to almost anyone at a vulnerable time in their lives.
Have you ever met someone you instantly connect with—someone who seems to know who you are, and what you need? A narcissistic sociopath is charming and magnetic, they appear to be perfect—the answer to your prayers. They are emotional vampires—the ones who use manipulation to seduce their victims. They have a keen ability to quickly identify your inner wound, your vulnerabilities, and appeal to your vanity and fears to bind you to them. They make you feel a part of them, something larger and somehow more alive.
. . . .
Persons with narcissistic personality disorder treat others as an appendage and source of supply, though they can never feel gratified. Just like a vampire story, a narcissist will siphon another’s life force in the attempt to fill the echoing emptiness they feel inside. When Nico doesn’t get his way, or someone disappoints him he becomes enraged and has a meltdown that provides him with a release of pent-up anxiety and euphoric high which empowers him in the face of feeling worthless. There can be no acceptable explanation for not responding to his (or any narcissist’s) immediate demands. In the book, the extreme drama Nico creates is a plea for validation stemming from his fear of loss.
