The crossing

If you didn't know my name is Dasja and I have a little brother Charlie who is as smart as a seven year old could be. We were messing around with some tools and equipment and then something odd happened. A mini lightning strike appeared and the next thing I knew there were people in old clothes surrounding us with wagons and odd weapons. They looked at us like we were psychos. With my vast knowledge of history and science I almost understood what had happened. My brother and I had time travelled. I suspect by the clothes and weapons that we are in Europe and it is around the time of the plague. There had too be a specific order of events for the doctor who discovered the cure to make it and I happened to get in the way. Oops.

I did it. I did the one thing that could change human kind. The question is how do I fix it? I have an idea but whether it will work or not is what worries me. I'm scared for Charlie more than anything. I don't know if he will make it. The plague tends to go for the young and the elderly. In order to save all of human kind I will have to go into dangerous situations but I have to take Charlie with me. I don't know if we can make it.
