Demon Kin — T.G. Ayer

When a business tycoon hires Mel Morgan to find his missing daughter, the SoulTracker is thrown headlong into twists and turns of unexpected deaths and unusual killers. But to find the girl in time to save her, she has to first understand the killer. Demonic or human killers? Mel can't decide which will be worse. Things get a little complicated when she has to help find both a Panther Alpha's mother, and a reluctant Djinn Queen. Add to the mix an evil spirit plus her mentor Samuel sending her terrifying messages in the Ether. Save him, or else. It's just all in a days work for a SoulTracker.
