"It's a little rudimentary, but this book helped to teach me what it is to be human," he says. "To be such a complicated, mysterious piece of biological machinery, and more amazing still, to have the capacity to analyze that machinery! That is a special thing, unprecedented in all of evolutionary history. Our ability to know about ourselves and the world is what makes us human."
He hands me the book and turns back to the computer. I look down at the worn cover and run my fingers along the edge of the pages. He makes the acquisition of knowledge feel like a secret, beautiful thing, and an ancient thing. I feel like, if I read this book, I can reach backward through all the generations of humanity to the very first one, whenever it was—that I can participate in something many times larger and older than myself.
"Thank you," I say, and it's not for the book. It's for giving something back to me, something I lost before I was able to really have it.
The lobby of the hotel smells like candied lemon and bleach, an acrid combination that burns my nostrils when I breathe it in. I walk past a potted plant with a garish flower blossoming among its branches, and toward the dormitory that has become our temporary home here. As I walk I wipe the screen with the hem of my shirt, trying to get rid of some of my fingerprints.
Caleb is alone in the dormitory, his hair tousled and his eyes red from sleep. He blinks at me when I walk in and toss the biology book onto my bed. I feel a sickening ache in my stomach and press the screen with our mother's file against my side. He's her son. He has a right to read her journal, just like you.
"If you have something to say," he says, "just say it."
"Mom lived here." I blurt it out like a long-held secret, too loud and too fast. "She came from the fringe, and they brought her here, and she lived here for a couple years, then went into the city to stop the Erudite from killing the Divergent."
Caleb blinks at me. Before I lose my nerve, I hold out the screen for him to take. "Her file is here. It's not very long, but you should read it."
He gets up and closes his hand around the glass. He's so much taller than he used to be, so much taller than I am. For a few years when we were children, I was the taller one, even though I was almost a year younger. Those were some of our best years, the ones where I didn't feel like he was bigger or better or smarter or more selfless than I was.
"How long have you known this?" he says, narrowing his eyes.
"It doesn't matter." I step back. "I'm telling you now. You can keep that, by the way. I'm done with it."
He wipes the screen with his sleeve and navigates with deft fingers to our mother's first journal entry. I expect him to sit down and read it, thus ending the conversation, but instead he sighs.
"I have something to show you, too," he says. "About Edith Prior. Come on."
It's her name, not my lingering attachment to him, that draws me after him when he starts to walk away.
He leads me out of the dormitory and down the hallway and around corners to a room far away from any that I have seen in the Bureau compound. It is long and narrow, the walls covered with shelves that bear identical blue-gray books, thick and heavy as dictionaries. Between the first two rows is a long wooden table with chairs tucked beneath it. Caleb flips the light switch, and pale light fills the room, reminding me of Erudite headquarters.
"I've been spending a lot of time here," he says. "It's the record room. They keep some of the Chicago experiment data in here."
He walks along the shelves on the right side of the room, running his fingers over the book spines. He pulls out one of the volumes and lays it flat on the table, so it spills open, its pages covered in text and pictures.
"Why don't they keep all this on computers?"
"I assume they kept these records before they developed a sophisticated security system on their network," he says without looking up. "Data never fully disappears, but paper can be destroyed forever, so you can actually
