No one likes a predictable story. Whether you are writing a romance, espionage, mystery, or any type of fictional writing, you want to make your stroy full of suprises. They don't have to be big, but no reader will want to be able to predict what and why something is going to happen. I have read stories that irritated me when I knew exactly what was going to happen next. I like reading a story that takes me on an adventure, where I am guessing what and why something will happen next. One of the "points" in reading is to get your brain thinking, and good stories get your brain juices flowing, making you guess what will happen next. I am reading a fantastic book now, and I find myself asking questions while I read. I hope this advice helps, I have lately adjusted my writing style to write a story like this.
