As a wildcat Shifter and leader of his Shiftertown, Eric Warden knows his own kind. When he sees Iona Duncan he realises that although she appears human, she is a half shifter wildcat living with a Collar; he also knows that if Iona fails to acknowledge her true nature and her mating hunger, it may kill her. Iona finds the mysterious and powerful Eric alluring, even though she has vowed never to reveal her Shifter side. But her mating hunger is rising and with Eric so close, she may not be able to resist.
