Sex, lies and vampires

Amongst the Dark Ones there is one they call The Betrayer, one who is doomed to hand his own kind over to a demon lord... for eternity. But now a small boy has been kidnapped, and it's up to Nell Harris - a Charmer (no, literally, that's her job) to rescue him. Problem is, she cant help but find The Betrayer a teeny, tiny bit attractive... is it possible he is not as soul-less as he seems, or has her penchant for bad-boys just gone into overdrive?
