Saxon’s investigation leads him to Calleigh Mc Gowan, a half-werewolf, half-Elven dancer who entrances him with her sensual moves and promise of carnal pleasure.She’s a sexy distraction Saxon doesn’t need-even if Calleigh has her own reasons for hunting down the rogue werewolf. But in order to catch the killer, they’ll have to put their lives-and hearts-on the line.
