He's what happens when bad guys switch sides
As an assassin, he lives on a razor's edge of losing it all every day, but since Cari Renata came into his life there is so much more to lose.
Cari Renata's sister is dead, or so she believes. And, Bry is the one who told her that horrific lie. Her sister is hidden among the Brax in Freedom Colony, and Cari can't know. He promised his brother he would protect both the women they love with the lie. Bryson will do that at any cost.
Cari owns the universe, or at least a small part of it. She runs a major broadcasting conglomerate that spans several systems, but she's an investigator at heart. Cari won't keep pushing at the terror attack that supposedly took her sister's life, and she's poked the wrong beast in going after Todari House.
Bryson may have to break a promise to keep a promise, and come clean about Mal Renata's real situation. When he does, it may cost him more than he ever expected.
