Cadence by Bill Ricardi

Zealots and gangsters and Voids, oh my. Sometimes working for the god of sex and music isn't all it's cracked up to be. 

Lucas Andrews, known as 'Lucky' to his friends, is on the run. As a Host, he willingly shares his body with the spirit of Izadore, one of Ihy's 72 sons and daughters from Ancient Egypt. Hunted by religious extremists, their music-inspired powers spiralling out of control, the pair flees to New York City in order to pursue the only course of action that they've been given: Find one of the legendary Muses of Apollo. 

But the big city offers big problems and precious few solutions. Just as Lucas and Izadore start to find personal and financial success, they're plunged into metaphysical chaos and mortal danger. Will they be able to find the right help and training in time? Or will the nebulous Void or their dogged pursuers catch up to the pair and silence them forever?
