So I've been spending a great deal of time working on a novel, and eventually I would like it to be a series. I'm about a fifth of the way through the first draft of the first book (about 25,000 words in) and I realized that I have a problem. The plot that I have in mind for the overall series becomes more centralized in each "book", meaning that the first book is a lot about the lives of the main character and his family/friends before the main plot, the second book is the main character trying to avoid getting involved in the main plot and while more of the main plot is present it's still a lot of about the lives of the characters, and the third book is finally the beginning of the overarching plot which continues through additional books. So the problem I'm currently experiencing is that the first book essentially has two very polar opposite plots. 1. The main story is mostly about love and loss of the main characters as they grow, mature, and graduate. A lot of what happens in the first book is extremely important for a few of the main characters down the line. But a lot of it also really isn't important to the "overarching plot", just important to story being told in that book. 2. The other half of the plot (which is the first conflict of many in the overarching plot and essentially what kick-starts it) is that the main character is the son of a great king and queen and he was sent away during a war so he would be safe. The antagonist is the son of the man who was at war with his father who believes his purpose in life is to finish what his father started and tries to kill the protagonist (now seventeen). This launches the main plot of the story later on, but it's only MAYBE 35% of the story being told in this first book (at this point. As mentioned, it's still very much a work in-progress). Long story short, here's my concern. I feel like I have an amazing story being developed in the lives on these characters and the way they interact, and the way they change as the story progresses. I'm worried that in this singular piece of work, the overarching story from later planned installments may appear more forced and out of place in this piece. Conversely, I worry that this book won't connect enough the plot of the later installments because it's not about the war and the battles to come, it's about the characters. I suppose you could say the first installment is very character-driven and so it spends enough time exploring their lives that I justify it existing as a standalone work,and the later installments are more plot driven. Make any sense? What advice could you give to me, fellow writers?
