I don't think there hasn't been a vampire book I haven't read and or liked but my favorite "evil" vampire has to be Spike from Buffy the Vampire Slayer. He was just wrong from the beginning lol plus the punk rock look wow.
Happy Thanksgiving! My favorite tormented hero is Roarke from JD Robb's In Death series because of his hard past.I also really like Lucan from Lynn Veihl's Darkyn Series as well.
I guess I just follow whatever world building rules the author sets up. Sometimes it works for me and sometimes it doesn't. I read to escape not give myself an headache because the science is wrong.
I always love young adult fiction it reminds me of what it was like to be just starting out when everything was brand new. This would make a great gift for my student worker.
