“Type O positive,” said Marcus, reading over her shoulder, “good cholesterol, good glucose; hmm, a very high hotness count, that’s interesting.”

“Yes,” Kira murmured, fingers flying across the screen, “but look at all those arrogance particles.” Marcus started to protest, and she laughed, tapping out instructions for a deeper scan. An option popped up for a “Full Blood Analysis,” and she tapped yes; she’d never asked for this much information before, and apparently there was a simple “everything on the menu” option. It made her wonder how life had been different in the old world, when computers were used for every aspect of life, and not just in the hospitals where they could generate enough electricity to use them.

Mere seconds later the computer offered a list of various electrolytes and glucose molecules and other little bits in the blood; it would take longer for a full analysis, calculating what, for example, the glucose density suggested about his liver health, but the computer would update those details as it went. The next set of notes to appear were genetic modifications; they had been so common before the Break that almost everyone on the island had at least a few. Marcus had the genetic markers for in vitro gene correction, meaning his parents had scrubbed his DNA for congenital diseases before he was even born. He had another marker in his red blood cells, signifying some sort of bone marrow modification, but neither Kira nor the computer could tell exactly what it was without a full bone sample. It didn’t matter either way; Skousen and the other researchers had already examined the gene mods as a possible source of RM immunity, but it was a dead end—if anything, it seemed to make the subjects more vulnerable to the virus, not less. Kira moved on and started taking 3-D photos of the blood, examining individual portions of it for anomalies, when the computer chirped a small alert, and a glowing blue rhombus appeared in the corner of the screen. She frowned, glancing at Marcus, but he only shrugged and shook his head. She looked back at the screen and tapped the alert.

A new section expanded across the screen, one brief sentence with a handful of pictures attached: 27 Instances of RM Virus.

“What?” Kira whispered. The number blinked, updating to twenty-eight. She tapped one of the pictures, and it flew up into a corner of the screen, enlarging to a 3-D representation of RM. It was a rough, fat sphere, highlighted in yellow to stand out from the background image. It looked putrid and menacing.

The number in the alert continued to grow: 33 Instances. 38. 47. 60.
