Paranormals (weres, vamps, witches and a null, the F protagonist). First in series. Audio. Not much romance/sizzle. 
 At 15 percent in, the female MC's inability to stick up for herself is pissing me off. Even for paranormal books, the predicaments the author puts her in are far fetched to silly. 
 At 60 percent in our heroine's lack of 'take-chargeness' simply gives me a dull headache. I'm plowing ahead. 
 Finally, done. The main female MC is a "null," a person who acts as a human force-field, cancelling out the paranormalness of others, such as witches and vampires who come within a few yards of her. 
 Dictionaries define a null as a zero or lacking legal or binding force. These are good definitions of Scarlett, too.
