Every author uses the mythology in a different way and we could debate the usage for many posts. We'll suffice it to say that each book is unique. One aspect that I found most relevant to this story was the use of a vampire's scent. During their initial meeting (pages 19-22) Eric emits an individual scent that seems to almost call to Angie. She is "lured" into ignoring the warning bells in her mind about what Eric is doing to her. Later she questions herself about her behavior and wonders if she was slipped some sort of drug. Each time they are together Angie notices Eric's scent.
Another "behavioral" quirk that Angie Notices about Eric is that he almost seems to read her mind. She often wonders if she is saying her private thoughts aloud. Eric doesn't use these things to harm her in any way and he doesn't seem like a vile vampire either. Both of these traits could easily be used for nefarious purposes and so it was nice to see them used for a nice vampire.
What is your favorite myth used in Once Bitten? Would it bother you if your boyfriend could read your thoughts or cloud your judgment? Do some myths fit better with good vampires or villains?
