Til Death 5 by Aryanna

The most important part of winning a war is identifying your enemy. Leroy Bly is in for the fight of his life, as friends turn to foes and love becomes a hate so powerful that it turns everyone into an Opp. There's no way out, and there's no going back. The only thing left to do is kill or be killed. Who will live and who will die?
Only God knows, and He's not telling.
Be advised that the eyes of the killer ain't always who you're looking for. The fight will be brutal, suspenseful, and TIL DEATH.
