I have a question about pacing. Specifically, I am curious about how to blend an epic fantasy tone with a thriller's pacing. Epic fantasy is often marked by large bits of world building and sharing. However, I have a story in mind that primarily deals with a father trying to save his kidnapped toddler from a cultish group trying to summon an evil being from the netherworld. The father has a limited time to track down, eliminate the bad guys, and stop the ceremonial magic. I have an idea that perhaps this could be a trilogy where the boy and his father become the central characters that fight against a being that is truly evil and could end the world. So, do any of you have any experience in blending to fairly contrasting styles, sweeping epic/thriller pacing? Or, if without that experience, know of any novels that attempt to do so. I feel as if Promise of Blood does pretty well at this any other novels?
