I'm working on a short novel that has two main stories. These stories belong to relatives from different generations, but of the same age.
So, although the book spans through 20-30 years, I'm more interested in showing each character's current situation, rather than those things that happened in between.
What would be a good approach, tool or technique for creating a smooth transition between both narratives?
About the story: It's a historical short novel, and it intends to show the repercussions of one person's past actions on a younger family member. It's written in third person, and it uses quite a few parallelisms between both stories. The historical moment is crucial, as this gap between generations is also a split between two very different political scenarios.
