The Edge of Chaos. The Edge of Chaos, #1

Brothers Nicky and Zavier Booth get thrown into a world of crime, intrigue, and danger when a deadly gangland assault on their father's auto garage leaves the brothers orphaned, homeless, and alone in the world with no one to rely on-or so they think. The boys don't understand this new world where the rules of law and order no longer exist. They'll have to use all their wits and resources just to survive-but the brothers have one thing to carry them through any danger.
They still have each other. Before they know what's happening, Nicky and Zavier get swept up in the conflicting loyalties and betrayals of high crime, Police investigations, and hidden agendas that come together to rob the brothers of all they have left-each other and their lives. Nicky and Zavier will have to defeat the forces amassing to take them down before their enemies take the brothers down first.
One side will reign victorious. The other side will be taking a one-way trip to the morgue.
