Dominion draft

Ake thought he had seen everything he needed to, being a time traveler. He had it all solved out. He knew how to save every single life of his friends and family. Going to the same time line over and over again, the last thing Ake expected was to cross paths with a sister he never knew, or to learn things about himself he never knew. Now along with new allies (his sister), comes new enemies.
This is the first story I actually ever started. But I haven't finished it or revised it. So this is a very rough draft. Advice is welcome. At the end of each chapter I'll put in mistakes I made or what I plan to change if there is any.
