Never underestimate the power of a good subplot. Or several.
Novels have more than just a single story weaving through the pages. There is the main plot of course, but at least one (probably more) subplot.
I'll deconstruct a novel a read last month to give you a better idea.
Main plot: A vampire (hero) and werewolf (heroine) are enlisted by police to solve the violent murders have six vampires, where werewolf DNA was left behind.
If the author had just written that book, it probably would have been short and simple. Nowhere near the 400 pages I read.
Sub-Plot 1: Vamps and wolves are trying to negoiate a truce, because both sides feel threatened by humans. Our hero is sleeping with one of the vamp negotiators. Our heroine is granddaughter of the leader of the wolves. Complications ensue.
Sub-Plot 2: Hero and heroine are attracted to each other, a huge no-no to their cultures. She risks banishment by being with him.
Sub-plot 3: Another wolf in her pack is threatening to challenge her grandmother as leader. He doesn't think that Grams can safely lead the pack any longer.
All of these subplots tie in to the main investigative plot, but they add meat to the story. Layers, characters, events, and twists that make it a solid, long novel.
And the novel is "A Taste of Crimson" by Marjorie M. Liu.
ETA: we posted at the same time, Kristie. Great minds...
