I love an epic tale as much as the next person. Stories that span generations and tell tales of grand adventures are stories in which I can get lost for hours. Usually meaning that I will be tired the next day because I couldn't be bothered to put the book down to go to sleep. But, there is one thing that I find nearly unbearable. When I discover, about two-thirds of the way through a book, that there is no way, without ruining the story, that the author can finish a tale in one volume I start to panic. That means a sequel! That means I have to wait! I don't wait well when there are stories on the line! What will happen to those wonderful characters that I have come to love? How will their problems be solved? Where will they go next? More importantly, how will I survive without knowing? Some authors, and publishing houses, are, I think, sensitive to this and release books on a fairly regular basis. But some, and I loathe to name names but, Diana Gabeldon when is your next Outlander book coming out? It's been years and I can't stand not knowing what is happening in Jamie and Clare's lives. What of Brianna and her family? AHH!!!
I'm just saying...
Here are a few of my favorite hate to wait series:
