vampire book im reading right now

i'm reading this book called
"piercing the darkness" (undercover with vampires in America today)
by Katherine Ramsland, its really good to be honest! it is in a documenter style but i think that makes it all the better warning if you plan on reading it after i post thins it gets very ummm sexual? there a lot of sex but to be honest the hole vampire community revolves around sex lol

still saying that it is a very good book and i recommend it if you interested in learning more about the vampire community and stuff like that but its just very rated +13 and up
