on Helping Writers become Authors:

What are some good hooks for your opening chapter? This is a question every writer must ask at the beginning of a story. How can we introduce the story and the characters in a plot-pertinent way that also deeply interests readers?
A good hook sets your book apart. It promises readers you’re going to deliver something worth their time—whether it’s a familiar genre romp or something they’ve never quite seen before. It signals you know what you’re doing and you’re offering a story that will keep them intrigued on every page.
