The Colonel, as William Brace is often called, is a solid, white-haired soldier with a firm step and a straight back. Brace spent his early career at Seymour Johnson Air Force Base in North Carolina before moving to Barksdale Air Force Base in Bossier Parish, Louisiana.

Brace has a fondness for Southern culture, and although he will deny it, he imagines himself a genteel Southern gentleman. His wife, Cora Brace, is soft-spoken, but she knows how to manipulate a man. Brace doesn’t understand life outside the military, and he has no patience for anything or anyone outside the chain of his authority.

We first meet Colonel Brace in Book 1 of The Human-Hybrid Project, Shattered by Glass.
