The Renegades Book 5: Setesh's Secrets

Humans are confusing, according to Xaphan, a fallen angel new to Earth.
Unable to hide their angelic wings, Xaphan is forced to stay at home unless fighting crime with their superhero team: The Renegades.
Until now.

A chance encounter with the Egyptian god Setesh has shown Xaphan that it is possible to hide their angelic nature and live among humans.  Setesh is even willing to teach Xaphan how to do it.  But gods of chaos never do anything for free, and what Setesh wants in exchange could change the balance of power on Earth forever.
