Chapter 1 - Deep Freeze

The red door slammed shut and a bolt was quickly latched as it suddenly thundered under an impact. The roars outside and heads bashing on the door made me cringe as I slid down the door and rubbed my arms. It was just the 4 of us against those... things.

The infected, those vile creatures that now seemed everywhere, screaming and slamming on whatever made noise or caught their attention. Cody growled at the noise outside. "SHUT UP DAMN IT!" He moved to where the bars that allowed what little view outside and cocked his pump-action shotgun and fired a few blasts making me cover my ears, splattering the heads and upper torso of the undead that hammered the door. I sighed as I looked up at him once my ears stopped ringing. "Cody, that is just going to piss them off and keep us up all night... give it a break. We're alive." I groaned weakly as I checked my weapon, a simple 9mm pistol and shook my head as I took out a cloth to gently clean it and forced myself to stand, went to a corner and sat down.

"Jessica, those things almost tore us apart!" Cody yelled at me, to which, I looked away and then down as I stopped cleaning my gun.

"Easy on her, we've all been stressed" Terence rubbed his forehead. "Cody sit down and breathe, ok?"

Cody looked away and walked over to the other woman, his sister Alexis to tend to her. I didn't really pay attention as I went back to my gun and winced a bit as I tried to stand up and take off my bag and start digging inside. "Was anyone hurt?"

Terence shook his head. "I'm good."

Cody sighed. "Alexis twisted her ankle. Its swelling, that charger almost got her; this is your fault Jessica!" He shot me a glare as he turned to face me. "You said that building was clear!"

"It was, Cody!" I yelled back. "It's not my fault it broke the door down while we were gathering supplies, be thankful it wasn't a tank! All we need is that monster of a creature storming inside..." I trailed off looking away as tensions died down. Distant, as I thought about my first experience with them...

I was in university, studying to become a librarian. Growing up I had an incredible passion for books, but as I grew older, I found more and more books didn't interest me as much. I never had enough time to read in those days, and the course reunited me with my childhood passion... They were some of the happiest days in my life.

It happened so quickly I still have to pinch myself, praying it was all just a dream. One moment I'm in class, the next I hear screams as people run for their lives. I didn't know what was going on, but I ran. Managed to get out only to see people running and attacking each other, it was terrifying. I fled; tried to get away from what chased me and only made it by getting on to a dumpster and shooting up a fire escape. I could see them climbing after me. One managed to get up and I panicked. I broke through the nearest window, wincing as the glass cut my skin. I spun around, grabbing a lamp off a dresser then swung with all my might at the... thing... whatever it was, striking it in its head. The skull splintered, spraying rancid blood and grey matter everywhere. I stumbled back, eyes wide and breath short and as blood dripped from my face.

How could I have done that? I just... killed someone! They were attacking me, I had to flee, to protect myself. Most of it was a blur after that. Ran into Terence not long after, Cody and his sister several days later. By then the city was in chaos. Up in Canada we don't have a lot of people like in the states, not as many infected, but with cities spread out and the cold climate, it was harsh for a lot of survivors to make it to places they could be safe. The strange infected, that screaming runner, the big hulking monster of muscle my friends called a tank... were but a few monsters that these things had at their disposal. I didn't even know if my parents were alive. Trapped in the downtown area where my school had been, we had struggled to get through the cold and the undead. A river bisected the city, making the only way across was a couple of bridges, which was sheer suicide to even consider, jammed up by both vehicles and the infected. The ice was too thin to cross so we had no place to go... Disheartening to say the least.

I snapped out of my stupor and looked around. I must have dozed off; everyone was sleeping and I got up slowly and looked out the barred window which kept the infected from getting in. Between the snow-covered ground and them shuffling everywhere waiting for noise, I ducked down and rubbed my arms, realizing I was freezing. I looked for a blanket and grabbed it and wrapped myself in it, teeth chattering fiercely.

"Dumb... C-c-cold..." I muttered as I worked on warming myself up; I regretted leaving my jacket behind, but what choice did I have? A piece of clothing or my life...

I took my gun and checked it carefully and made sure everything was working. Thank god Terence used guns as part of a hobby, or I'd be stuck with a melee weapon, I was clumsy enough as it is... not cut out for a lot of this strength business. My real skill was first aid, I took a course when I was younger, still remembered a lot, which at least made me useful. Teeth chattering finally slowing down I felt myself slowly drifting off to sleep...

I woke to the cries of pain from Alexis, shooting up, I grabbed my kit we had salvaged. A first aid kit, and ran over and almost shoved Cody aside as I checked her out. "She's going to need to keep off it for a while. We need to stay here until she can at least walk, or find a vehicle we can take and get her to a safer place."

Terence shook his head. "A vehicle... not likely, none of us can hot wire"

Cody growled. "Easy Alexis." He tried to calm her cries of pain as I shook my head.

"This isn't good at all..." I muttered as Cody glared at me. "We are not leaving my sister behind!"

"Easy Cody, we'll get her out of here" Terence put a hand on his shoulder, to which he responded by shoving it away.

"Terence, we will need to get something to help her with the pain, or she's going to just make it worse for us all." I ignored Cody's harsh glare as Terence nodded. "We also need food... We should head out and get something?" He looked to me as if my answer would be the final decision. I sighed getting up; I wasn't the leader, he was but I nodded just to help reassure him in some way. "Cody, you stay here with Alexis ok? We don't want her getting hurt and if something comes in, you'll have to defend her"

"I can defend my sister, Jessica!" Cody snapped as he cocked his gun and I backed away raising my hands nodding. He was just 19, his sister 18. He was so hot-headed it was disturbing sometimes, the little time we had together I felt like he was going to just shoot my head for saying something wrong. I was 24; Terence slightly older at 26.

I nodded to Terence as we headed for the door, readying myself, we quickly unbolted the door and stepped out, Cody closing and locking it behind us. I wondered if we came back, would he let us back in? I put my pistol into its holster and took out a crowbar I had tied my bag and got ready, I didn't want to make noise, and they always loved noise... Terence did the same using an axe and we went to work going through the apartment complex we had taken shelter in. It was dangerous but it was all we had, a student's residence near the university. Circles were a common problem for me, I had a horrible sense of direction. I stuck close to Terence who struck at an infected and sliced his head off, the infected roared and charged at us. I swung my crowbar at one smashing in its head while Terence shoved two back and slashed with his axe. I hated tight corridors. Trying not to hit a fellow survivor when you're both swinging weapons while infected rushed you was almost as terrifying as the dead themselves...

They kept coming for what felt like hours, but less than a minute had passed until an eerie silence settled in the building. I looked at Terence, panting. "Let's see if we can get to the schools Infirmary?"

He shook his head. "Too dangerous, we are already risking our lives in here. We are lucky that someone even made a safe room, or we'd be boned!" He had not finished talking when something burst through the door behind us, coughing and hacking. As I turned and yelled "What the hell is that!?" It heaved, throwing a tongue that struck and wrapped around me, dragging me towards itself as I screamed. Terence took out his ranged weapon, a hunting rifle, and fired causing whatever that thing was to explode, and I coughed and gasped for air as I got caught in a cloud of smoke. I stumbled forward and grabbed on to Terence, trembling uncontrollably. "Oh god, thank you Terence." I hugged him tightly as he brushed my hair back gently. "Let's keep moving..." We stepped out into the main floor of the residence, and saw the reception area swarmed with the infected. We took aim and opened fire; unloading bullets and reloading until nothing moved.

I swallowed and took out a bottle of water, taking a quick drink as Terence and I slowly headed out into the cold. He took my hand and pulled me along as we headed to a small store just off to the right of the residence building. It was the store the campus used for supplies, some clothing, and books for classes. Determined to bring me inside, Terence pointed to some of the coats and other warm articles of clothing for sale. "We should ready ourselves for whatever comes, even the cold. We didn't get the chance earlier and we probably won't again." He said as he grabbed a jacket and put it on after removing his backpack.

I picked out something for myself, Cody, and Alexis. Out of the corner of my eye, I caught movement as infected came toward us from the store interior. I turned and opened fire, which wasn't my brightest move as it brought more of them at us. We defended ourselves yet again until the building was clear, smoke drifting from our weapons.

We gathered a couple more things, such as water bottles that could be refilled and headed out. "Where to first?"

"There's a pharmacy down that street in that grocery store, we can check and see if it's been looted or not." He suggested and I nodded, following him carefully. I reloaded my gun making sure I had a full clip, something he taught me to do between fights. Bolting across the street and down the sidewalk, things seemed fairly clear which I thought was a sign of something at least good, and hey, I was no longer freezing. I laughed a bit to myself as Terence carefully approached the store with me in tow, and started to scout almost instinctively while I covered him. So far so good I told myself over and over as I looked around. As Terence moved through the parking lot, a few steps ahead of me, I turned to a car and jerked into him, stumbling as I saw a dead body inside and gasped... It was the worst mistake ever...

Terence stumbled away from me and bumped into a car that shot off a terrifying wail, followed by roars echoing through the city. I paled as he screamed. "RUN!"

They were on us quickly, so fast it was a maelstrom of infected as he got us into a chokepoint and we fought with desperation on our faces...

I only caught the growl behind me as we managed to gain the upper hand. Something behind us made a terrifyingly loud noise, I turned to confront it as Terence was focusing with the infected that were rushing us head on. As I turned, a being slammed into me hard and threw me to the floor, winded and dazed, gasping for air as the beast growled over me. Showing sharp teeth, it grabbed on to my side and I felt something dig in. The shock was... enough to make me blank out and the scene around me grew hazy. Terence, having just killed the last of the infected, turned to me and cried my name. As he turned and threw his axe towards us, narrowly missing the thing on top of me which leapt away to avoid the attack. As it leapt, something pierced my skin and I screamed in pain. Terence grabbed his gun and fired a few quick shots as the thing retreated into the darkness, leaving me coughing on the ground as I could feel wetness on parts of my body. Barely moving, I coughed again and looked up. "T-T-Terence..." I tried to move my hand as he rushed to me and grabbed his weapon quickly. The words that followed were a blur, but I saw Terence taking aim at me after a few with his gun. I tried to tell him not to but no words left my mouth... I saw the smoke fly from the barrel as something screamed loudly and I blacked out...

Yay chapter one done :D on to chapter 2
