Sometimes the depths of love can only be understood when lost...

Scientist and vampire Sian Tallant loves a human doctor – a relationship that's taboo in the world she comes from. She knows she has to break both of their hearts by leaving him forever...before he finds out the truth about her dark heritage.

Unwittingly, Taz follows her into vampire territory, where he's captured and learns that the world isn't the safe place he's always believed it was.

To save him, Sian has no choice but to go up against her own kind. In doing so, she takes the most dangerous risk of all – that the person who matters most to her will only fear and loathe her when he discovers who and what she really is.
