Ok so I've been brainstorming for a while on my werewolf military novel and I can't seem to put the time lines, MC's together. At first I was thinking, focus on the main MC's which would be the fraternal twins male and female separated at birth. They are the important MC's but my other MC's are just as important. I'm building a family tree and I was thinking of doing this all in chronological order. First would be about a young British or American hero soldier with an elite troop team along side the allies in WWII. The hero and his team infiltrate a camp guarded with Nazis. A young female Polish prisoner escapes and follows the hero and his troops, unknowingly she's become a werewolf and they discover her powers, which she helps join them and fight. When it's over and they've won, the hero soldier and werewolf girl are supposed to meet and start the family tree. I just can't figure out what to do next. Should they go their separate ways after the war as covert mission operatives and then meet on a spy mission in the 60's and then have their son or should they meet again in the 50's and have the son? Should they fall in love and have a son right after the second world war before becoming secret agent spies? Their son is supposed to have a son of his own in the 70's or 80's maybe with a female Russian spy and then THAT son is supposed to have the boy and girl fraternal twins in the 00's with a woman from Nepal/India/Tibet or something, which will be the main MC's being the latest carriers of the werewolf powers. Does anyone have any advice that can help me? Thanks again.
