Wings of the Fallen — Anthony Pryor

A mysterious woman's secret can save or destroy two worlds.

Alex St. John is the Shepherd, a goddess's champion who protects the world from things that go bump in the night. Now he's caught in a war between billionaire Roger Dandridge, a family of brutal street thugs, and a motorcycle gang made up of millennia-old demons. A beautiful woman holds the key, and Alex must help her reclaim a lost heritage that could save the world -- or doom it.
