‘We’re getting news back from some of the others who’ve already got to the Lunar Array,’ said Lester. ‘They got detained at first, but then they were allowed through to Da Vinci, along with almost everyone from Copernicus City. From what we’re hearing, it looks like most of whoever they want to bring through from Earth is already through.’ His expression became troubled. ‘But I can’t stop thinking about those millions of refugees back in Florida. It makes no damn sense, just leaving them there to die like that. Couldn’t they at least save some of them?’

‘I don’t know,’ Saul admitted.

‘Oh, it makes sense, all right,’ said Amy, ‘in a twisted, callous kind of way. The colonies haven’t been around all that long, and most of them can only sustain small populations, as it is – especially places like Newton, with the sealed biomes. They’d be hard pushed to cope with even a small increase in their populations.’

‘You’re sure of that?’ Saul asked.

‘Think about it,’ she said, her tone flat. ‘It’s what they call a cold equation. There just isn’t enough food, water and air to go round. It’s the logic of the lifeboat: if you’ve got a lifeboat big enough for six people but seven hundred are drowning all around you, there’s no way you can get more than a tiny fraction of that number into the lifeboat without sinking it and drowning everyone.’

She reached over the back of her chair to touch Saul’s arm. ‘You did a good thing getting those files here, son. There’s nothing we can do for those people back there, much as it makes me sick to admit it, but that doesn’t mean we can’t do our damnedest to make sure the ones responsible for all this will pay for what they’ve done.’

Saul came to a decision and pulled himself into the seat directly behind Amy’s. ‘There’s something I need to tell you both. When we get to the Moon, I’m going to try and shut the Array down – collapse every one of the wormholes.’

‘St it down?’ said Lester, a confused look on his face. ‘Is that even possible?’

‘Maybe Lester and Amy have got enough on their plates right now,’ interrupted Mitchell, pulling himself through from the lander.

Saul jerked his head around in surprise. ‘You’re awake.’

‘No,’ insisted Amy, ‘I want to hear what Saul has to say.’

Saul turned back to her. ‘Take a look at the files I just sent you. Particularly the video sequences listed under “Copernicus”.’

Amy stared sideways at a bulkhead, as Mitchell floated down to join them, with a look of disapproval on his face. ‘Okay, I’ve got it.’ She frowned. ‘Hey, it looks like—’

‘Like something’s completely devastated the entire city. Is that what you’re seeing?’
