In my current work, I'd like to divide it up in 3 parts. The first, in the eye of one protagonist, happens at the same time as the 2nd part, from the eye of the other protagonist. They are far away while the events happen and each has their own storyline. (They meet in Part 3) Will it be too confusing to do this? It's a fantasy novel, so I can't just put a date in the corner and leave it at that. Any suggestions?
