I took Anastasia Seun's great on-line Chapter Book class this winter. (Both the reading and the writing part). Now, I'm working on drafting the chapter book. Thanks to the class, I have a great outline to follow and a strong story line. But...I'm thinking my story doesn't have enough of a "hook." The character's voice is strong, and the structure seems good, but it seems to be missing that "extra something."
When I read so many of the chapter books, there seems to be a hook. For example, The George Brown series has his secret burp. The Katie Kazoo series has her ability to change into other people and animals.
Does anyone have any tips for "hooks" in chapter books? Or are there successful series without the big "hooks?"
