I'm starting a fantasy-type story, which is centered around a group of four friends who are put together for a mission from the spy service they're in. Initially, I wasn't going to have that many sub-plots, seeing as I only want to write one book (I hope), but I was discussing my plans with my friend for feedback, and she suggested quite a few ideas. Thing is, I like the ideas, but a lot of them are way too cliche (like one of the four secretly being the heir to the kingdom but he doesnt know that). I'm thinking of knocking that particular idea off. But I wanted to ask; what would be a reasonable amount of subplots for a story like that, that's fantasy and action/adventure and suspense? I can't have, like, a twist every five chapters. I think my brain would explode from plot overload. I need to tell those plot bunnies to lay off D: Or should I just try for more than one book? I'm not too sure about that idea though - seeing as what I've planned is only enough for one. So yeah. Thoughts?
