I think if Kathy was a lousy writer and her stories less engaging the frustration would be less. The problem is that she is a VERY good writer with characters that draw one in to the story and storylines that leave the readers waiting at the edge of their seats for more. Without fail the stories Kathy starts on this forum and elsewhere have been a delight to read up until the very last word--and sadly that last word available sometimes leaves the characters (and readers) hanging, usually at the edge of a much bemoaned "cliff".
I think Genevieve is expressing frustration with feeling as though she (and others) have been "left hanging". I can relate, and have sworn off starting new Kathy stories till they are finished for that reason. I've read and followed ALL of her stories before she ever started posting here, and more than half are currently without an ending. If the characters didn't come to life so fully, or the story was less enthralling then it might be easier to handle; the readers would have less of the ICU waiting room feeling as they breathlessly wait to see if their favorite character(s) survive.
I understand that Kathy has a life and kids and business to run, and that responsibilities take priority. Intellectually I can handle the concepts of writer's block and time restraints. But it's the emotional bonds that readers form with her characters and stories that make her such a gifted writer, and those same emotional bonds lead to distress when the story lacks closure. Will Sissy escape the zombies? Will Del and Mark ever get married? And what about poor Leah? Lots of unanswered questions about people who the reader cares about, even though they are fictitious.
I'm not saying Kathy is a flake, or irresponsible, or any of the other comments that have been thrown about in fits of pique and disappointment; contrarily she is a woman with great amounts of responsibility on her plate and she tends to become overloaded as so many of us often do. As her readers we just have to accept that her writing is lower on the priority list than real life, and then deal with it. Start her stories knowing that they may hang in limbo, or don't start them.
But don't be the sheep shushing the child who says "the emperor has no clothes" as he struts naked down the street. Incredible talent and ability aside, after 5 years of unfinished stories it begins to look like a trend.
ETA: And yes, when I finish one of my many started stories I WILL post it. But not till then.
