Here are some links to several entries on the Crowe's Nest blog -- the blog of agent Sara Crowe where her list of authors take turns posting articles about writing.
First, one from Mary Atkinson about the Controlling Belief of a character -- that which forms the background reason for all the character does. This is different from a character's goal.
Secondly, another post by author, Lisa Schroeder, from this same blog giving a writer's view of the American Library Association's Summer Conference. Yes, the same conference I wrote about last week.
Happy reading and writing.
