Okay, so I'm trying to weave two stories together separately so that they both start out differently but the characters end up interacting with each other, but the stories end differently. To clarify, the first one is about a girl who was a failed genetic engineering experiment. It's in first person POV, and she goes on an adventure to team up with a group called the Resistance that strives to stop a tyrant from invading their country, yadda yadda yadda. The second one is going to have two main characters, a boy and a girl, and so it's in third person. The girl is the tyrant's fiancee, but later on she finds out what a horrible person the tyrant really is. The boy is one of the tyrant's personal servants, and he was the one who was telling the tyrant how to make the girl fall head-over-heels in the first place. The two end up escaping from the tyrant somehow, and they're in the engineered girl's territory when the fiancee is recognized and they're both stopped by the Resistance. Later on they all realize that they want the same thing, so they team up and work together and save the world. The end. Oh yeah, and there will also be two romantic plots involved, but one happens early on in one story and the other comes almost at the end of the other story. Okay so now my question is this: How could I avoid making the two stories have the exact same events happen from the time that they meet on? I know each set of characters has their problems to work out, but wouldn't it get boring to read the same thing twice in different books?
