Sam, no!” Edilio snapped.Sam missed a step, then stopped. He looked at Edilio, puzzled.“We’re scattered. And we can’t risk you. You die and the light dies with you.”“Are you out of your mind? You think I’m going to let Drake come in here and take Diana?”“Not you, Sam. Dekka, yes. Orc, yes. He’s out there, too. And send Jack as well. Anyone but you.”Sam looked like he’d been punched. Like someone had knocked the wind out of him. He blinked and started to say something and stopped.“You aren’t replaceable, Sam. Figure it out, okay? It’s going dark and you make light. So this isn’t going to be your battle. Not now. It’s on the rest of us to step up.
