Kerry Logan's restless nature often drives her out into the night, seeking solace in the crush of people at her favourite dance clubs. When a fire breaks out in a club and Kerry finds herself a hero after carrying many people to safety, she wonders: was it just adrenaline, or did this sudden super-strength come from something deeper? Ranulf Thorsen recognizes Kerry as a Kyth, a human-like species descended from Viking warriors that thrives on the life energy of humans. Physical contact greatly heightens the sense of warmth and well-being, which is why they enjoy crowds. Ranulf is the enforcer for Talion, warriors who hunt down rogue Kyths who thrive on human pain and suffering. When a rogue Kyth tries to harm Kerry, Ranulf come to her aid. But there is much that Kerry must learn and accept as a newly found Kyth -- including how to protect her heart from darkly dangerous and sexy Ranulf.
