"It's not that bad yet," I said. "Our parents are working on it. They'll figure it out. We're not all going to die."

"Well, you're not going to die, at least," Gretchen said.

"What does that mean?" I asked.

"If things really go swirling, the Obin will swoop in and take you out of here," Gretchen said. "Although if all of the Colonial Union is really under attack, I'm not sure where you're going to end up going. But the point is, you have an escape route. The rest of us don't."

I stared at Gretchen. "That's incredibly unfair," I said. "I'm not going anywhere, Gretchen."

"Why?" Gretchen said. "I'm not angry at you that you have a way out, Zoë. I'm envious. I've been through one attack. Just one missile got through and it didn't even explode properly, and it still did incredible damage and killed someone I care about and everyone in his family. When they come for us for real, we don't have a chance."

"You still have your training," I said.

"I'm not going to be able to engage in single combat with a missile, Zoë," Gretchen said, annoyed. "Yes, if someone decides to have a landing party here, I might be able to fight them off for a while. But after what we've done to that Conclave fleet, do you think anyone is really going to bother? They're just going to blow us up from the sky. You said it yourself. They want to be rid of us. And you're the only one that has a chance of getting out of here."

"I already said I'm not going anywhere," I said.

"Jesus, Zoë," Gretchen said. "I love you, I really do, but I can't believe you're actually that dumb. If you have a chance to go, go. I don't want you to die. Your mom and dad don't want it. The Obin will hack a path through all the rest of us to keep you from dying. I think you should take the hint."

"I get the hint," I said. "But you don't understand. I've been the sole survivor, Gretchen. It's happened to me before. Once is enough for any lifetime. I'm not going anywhere."

"Hickory and Dickory want you to leave Roanoke," Dad said to me, after he had paged me with his PDA. Hickory and Dickory were standing in the living room with him. I was clearly coming in on some sort of negotiation between them. And it was also clearly about me. The tone of Dad's voice was light enough that I could tell he was hoping to make some point to the Obin, and I was pretty sure I knew what the point was.

"Are you and Mom coming?" I said.

"No," Dad said.

This I expected. Whatever was going to happen with the colony, both John and Jane would see it through, even if it meant they would die with it. It's what they expected of themselves as colony leaders, as former soldiers, and as human beings.

"Then to hell with that," I said. I looked at Hickory and Dickory when I said it.

"Told you," Dad said to Hickory.

"You didn't tell her to come away," Hickory said.

"Go away, Zoë," Dad said. This was said with such a sarcastic delivery that even Hickory and Dickory couldn't miss it.

I gave a less-than-entirely-polite response to that, and then to Hickory and Dickory, and then, for good measure, to the whole idea that I was something special to the Obin. Because I was feeling saucy, and also because I was tired of the whole thing. "If you want to protect me," I said to Hickory, "then protect this colony. Protect the people I care about."

"We cannot," Hickory said. "We are forbidden to do so."

"Then you have a problem," I said, "because I'm not going anywhere. And there's nothing you or anyone else can do about it." And then I left, dramatically, partly because I think that was what Dad was expecting, and partly because I was done saying what I wanted to say on the matter.

Then I went to my room and waited for Dad to call me again. Because whatever was going on between him and Hickory and Dickory, it wasn't over when I stomped out of the room. And like I said, whatever it was, was clearly about me.

About ten minutes later Dad called for me again. I went back into the living room. Hickory and Dickory were gone.

"Sit down, Zoë, please," Dad said. "I need you to do something for me."

"Does it involve leaving Roanoke?" I asked.

"It does," Dad said.

"No," I said.

"Zoë," Dad said.

"No," I said again. "And I don't understand you. Ten minutes ago you were happy to have me stand here in front of Hickory and Dickory and tell them I wasn't going anywhere, and now you want me to leave? What did they tell you to make you change your mind?"

"It's what I told them," Dad said. "And I haven't changed my mind. I need you to go, Zoë."

"For what?" I said. "So I can stay alive while everyone I care about dies? You and Mom and Gretchen and Magdy? So I can be saved when Roanoke is destroyed?"

"I need you to go so I can save Roanoke," Dad said.

"I don't understand," I said.

"That's probably because you didn't actually let me finish before you got on your soapbox," Dad said.

"Don't mock me," I said.

Dad sighed. "I'm not trying to mock you, Zoë. But what I really need from you right now is to be quiet so I can tell you about this. Can you do that, please? It will make things go a lot more quickly. Then if you say no, at least you'll be saying no for the right reasons. All right?"

"All right," I said.

"Thank you," Dad said. "Look. Right now all of the Colonial Union is under attack because we destroyed the Conclave fleet. Every CU world has been hit. The Colonial Defense Forces are strained as it is, and it's going to get worse. A lot worse. The Colonial Union is already making decisions about what colonies it can afford to lose when push comes to shove."

"And Roanoke is one of those," I said.

"Yes," Dad said. "Very definitely. But it's more than that, Zoë. There was a possibility that I might have been able to ask the Obin to help us here on Roanoke. Because you were here. But the Colonial Union has told the Obin not to help us at all. They can take you from here, but they can't help you or us defend Roanoke. The Colonial Union doesn't want them to help us."

"Why not?" I asked. "That doesn't make any sense."

"It doesn't make sense if you assume the Colonial Union wants Roanoke to survive," Dad said. "But look at it another way, Zoë. This is the first colony with colonists from the CU rather than Earth. The settlers here are from the ten most powerful and most populous Colonial Union worlds. If Roanoke is destroyed, all ten of those worlds are going to be hit hard by the loss. Roanoke will become a rallying cry for those worlds. And for the whole Colonial Union."

"You're saying we're worth more to the Colonial Union dead than alive," I said.

"We're worth more as a symbol than as a colony," Dad said. "Which is inconvenient for those of us who live here and want to stay alive. But, yes. It's why they won't let the Obin help us. It's why we don't make the cut for resources."

"You know this for sure?" I asked. "Someone told you this when you went back to Phoenix Station?"

"Someone did," Dad said. "A man named General Szilard. He was Jane's former commanding officer. It was unofficial, but it matched up with my own internal math."

"And you trust him?" I asked. "No offense, but the Colonial Union hasn't exactly been on the up-and-up with us lately."

"I have my issues with Szilard," Dad said. "And so does your mom. But yes. I trust him on this. Right now he's the only one in the whole Colonial Union I actually do trust."

"What does this have to with me leaving Roanoke?" I asked.

"General Szilard told me something else when I saw him," Dad said. "Also unofficial, but from good sources. He told me that General Gau, the Conclave leader—"

"I know who he is, Dad," I said. "I've been keeping up with current events."

"Sorry," Dad said. "He said General Gau was being targeted for assassination by someone in his own close circle of advisors, and that the assassination would happen soon, probably in the next few weeks."
