I used multiple POVs in my three completed novels and my first published book has 26 POV characters. I didn't set out to use so many, but this method suited the story and I have yet to have a reader express any confusion, so I discovered it is possible to tell a coherent story in this way. The next two novels 'only' have half a dozen POV characters each.

Strangely enough, my WIP is in first person, which is very challenging!
