Conspiracy of Angels

Set in a secret world of angels and demons, this action-packed novel blends biblical mythology with all the trappings of urban fantasy, mystery, and paranormal fiction
 
When Zachary Westland regains consciousness on the winter shores of Lake Erie, his memories are gone. All he has are chaotic visions of violence and death—and a business card for Club Heaven.
 
There, Zack finds the six-foot-six transexual decimus known as Saliriel and begins to learn what has happened. Alarming details emerge, of angelic tribes trapped on Earth and struggling in the wake of the Blood Wars. Anakim, Nephilim, Gibburim, and Rephaim—there has been an uneasy peace for centuries, but the truce is at an end. 

With the help of his "sibling," Remiel, and Lilianna, the lady of beasts, Zack must stem the bloodshed before it cannot be stopped. Yet if he dies again, it may be for the final time.
