This is the first book in the SPECTR series and it is available right now as a free download from Kobo Books. There is Caleb, the unregistered paranormal, Gray, a wandering vampire-like spirit who becomes trapped in Caleb's body and John, the federal agent/exorcist. There is a case of a murderous demon that needs solving. Throw this all together with Jordan Hawk's easy to read style of writing and BAM! We have a winner. So much of a winner that I was barely 3/4s of the way through it and I was back at Kobo buying the rest of Series 1.
So. Much. Fun!
