A/N: Please note, this book, Memento Mori, is book 2 of a planned trilogy. Though set in the Divergent world, the story diverges dramatically when Tris chooses Erudite instead of Dauntless. I would strongly recommend reading book 1, Hamartia, first. Thank you for reading and I look forward to your comments and suggestions! In response to Hope - some of you are a bit worried about the title. Memento Mori means 'Remember (that you have) to die'. Don't get too nervous! It might mean deaths of other people (e.g., neither Tris or Four), or it might mean deaths of old selves, and rebirths...

From Tobias' Perspective

I have been fighting and drowning for what seems like years, centuries even. But I am awake now. I don't know where I am. The light is too bright, and I close my eyes again to shield them from it. I think I am in a hospital room. I can hear a faint beeping noise. There are bandages on my head, and even slight movement send waves of nausea coursing through me. My mouth feels like it is full of cotton. What happened to me? I struggle to remember. And then I do. Tris. It all comes flooding back, and I am once again drowning. I remember Samhain. I remember her parents, lying dead on the warehouse floor, and she is bent over them, shaking. I remember going with her to Erudite. Oh God. I remember Eric, beating me. I remember fear, horrible fear, its black tentacles squeezing my chest, making it hard to breathe. It's hazier, after that. I can't tell what is real. I am lying on the floor, Tris' face hovering over me, and I am struggling to figure out what she is saying. I can't hear her. Her face is replaced by the face of my mother. She is stroking my hair, and calling me her sweet boy. I try to get Tris' face back, but I can't.

I open my eyes again, and I slowly realize where I am. I'm in Evelyn's hospital. I try to speak, but it's like I'm underwater. Tris. The beeping gets faster.

"He's awake. Go get Evelyn." It's a man's voice. I hadn't realized there was anyone there.

I hear footstep tapping quickly on a hard floor. And then my mother is there, her face coming into view like it had before, but this time, it is in sharper focus. She is smiling.

"Tobias, can you hear me?" Who is Tobias? I remember now. I am Tobias now. Who was I before?

I work my mouth, trying to loosen it, but nothing comes out. She is talking again.

"I knew you were a fighter, Tobias. You've come back to me."

"What happened?" I finally get something out.

Her face darkens now I remember that look. "You were tricked into going to Erudite. By that girl. They tortured you to get Marcus to talk. But we managed to rescue you."

"Tris?"

"It's OK Tobias, you're safe here. Safe from her."

I try to process this, but it's too confusing. My words are clearer now, though.

"I have to get up."

She smiles at that. "You'll have to wait a few more days. They had to remove a piece of your skull – your brain was swelling. They replaced it yesterday. And you lost your spleen and part of a kidney. They tell me you'll patch up, though. Good as new."

"How long…?"

"Have you been here? Five days."

My mind reels at this news.

"Tris?"

"You're safe here. I'll never let something like that happen to you again."

"Where's Tris?"

My insistence bring a cloud across Evelyn's face. "In Erudite, I assume." She snaps. "With her cousin, no doubt."

"There was a bomb…"

"Jeanine had someone plant it in Dauntless, and blamed it on the Abnegation. The Dauntless attacked Abnegation, and captured Marcus and several Divergents." A gleam of satisfaction flits across her face. "She was too stupid to figure out where we were really hiding."

"I didn't tell her…"

"Shhh. I know. You were brave. My sweet boy."

"I was afraid…"

"You're here now. Everything will be OK. Get some rest."

She leaves now, and they dim the lights. I close my eyes, and memories start to overwhelm me. The Samhain bonfire. Tris. The smell of blood in the warehouse. Tris. Am I dreaming now? I can't tell. I wish Zeke would stop running and put me down, it hurts too much. There are rows and rows of bookshelves. I can hear Tris now. She's telling me not to die. I want to, though. What did she call me? I remember now. Four. I used to be Four.
