two vampire romance books hopefully someone knows this series
1 1st book female vampire-slayer might be a vampire
2 1st book hero is suppose to be a rouge vampire
3 1st book heroine meets hero in a cemetery
4 know there are 2 books in series maybe more
5 2 book the hero thought he was a rouge vampire
but finds out the rouges lied to him about it in first book
6 heroine in second book is friends with heroine in first book
7 is possible that 1st heroine gave her blood to 2nd heroine
8 both heroines battle vampire 1st heroine has powers, 2nd heroine I'm not sure about

Thanks in advance

Sounds like Jeanine Frost's Night Huntress series.
