Crumbled Colossus — Heather Fleming

Sixteen years ago, the demon knight Apollo St. Jude disappeared. His son Abdiel has been trying to find out what happened to him ever since.

Just as Abdiel is on the verge of getting his answers, he and his sister receive an urgent call for help. The Gormogon Order is spiraling out of control. With many of its gargoyles deserting and the rest hunting them down, the streets of Rome are turning into a battleground.

All the while, an ancient secret waits to be resurrected - and once it is, Abdiel's life will never be the same again.
