So I'm finally getting how people feel when they have an impossible dead line approaching. I've realized I barely have enough to enter my partial manuscript and my editing busiess is chaging my entire plot! I've been working a bunch on POV character and have considered revamping everything I have to a different POVcharacter. I really want to work with multipul POV characters during different scenes and my book(Writing Fiction for Dummies) doesn't go over that. I think they call that head hopping but I've read a bunch of stuff with what I"m talking about and it worked really well. My problem is the transitions from one scene to another with a differen POV character. Can anyone help?
