I thoroughly enjoyed this story about Marc, the vampire Sire and Blake, his Childe and lets not forget the human, Kate.  Marc and Blake have been fighting demons but Blake seems to not see it as a responsibility but more as fun.  Marc is frustrated that Blake can't see that to protect the humans IS what's important, that humans are important.  When they meet Kate and her fellow human fighters while fighting a group of demons, they are taken back by Kate to the human compound, where they are greeted with not quite friendly faces.  Marc is intrigued by Kate, her boldness, her strength and by her beauty.  He knows it's not safe to get involved with a human and sees Blake's growing attraction to Kate as a threat to their very well being.  Kate is also torn by her attraction to both Marc and Blake.  She's distracted by them in the field which could prove deadly but she also knows they need Marc and Blake's help in fighting the demons.  Blake has some personal "demons" of his own to confront and deal with in his life as does Marc.  Secrets that both have that make their relationship difficult.  I'll not share any more but just say this is a wonderful story and I can't wait to read the next in the Blurred Trilogy.
